Retirement Calculator Python Program
) m_string = input('Enter the object's mass in kilograms: ') m = float(m_string) v_string = input('Enter the object's speed in meters per second: ') v = float(v_string) e = 0.5 * m * v * v print('The object has ' + str(e) + ' joules of energy.' ) To shorten a program, it is possible to nest the input statement into the float statement. For example these lines of code: milesDriven = input('Enter miles driven:') milesDriven = float(milesDriven) Perform the same as this line: milesDriven = float(input('Enter miles driven:')) In this case, the output of the input function is directly fed into the float function. Either one works, and it is a matter of programmer's preference which to choose. It is important, however, to be able to understand both forms.
Comments are important! (Even if the computer ignores them.) Sometimes code needs some extra explanation to the person reading it. To do this, we add “comments” to the code. The comments are meant for the human reading the code, and not for the computer. There are two ways to create a comment. The first is to use the # symbol. The computer will ignore any text in a Python program that occurs after the #.
The Best Retirement Calculators. Notes/Features: I’ve included brief notes on the features of each program, so you can get the flavor of its functionality.
They intend to save another $1000 per year for the next 10 years at which point they will stop making any additional deposits into their account. However, they may be 20 years away from retirement. Your program should be able to account for these varying inputs and calculate the correct future value of their account at retirement' Here is my code so far: def main(): print('Welcome to Letmeretire.com's financial retirement calculator!' ) import random num = random.randrange(10000) principal = int(input('How much are you starting with for your retirement savings?'
Download uefa champions league fantasy app. Keep up the great work, -Dwayne. Unfortunately the dark side of this whole retirement planning business is that the results often vary significantly, depending on the calculator and the planner. That’s because modeling the future is complex, and requires a lot of assumptions. (My previous retirement calculator articles document this in detail for both an and a more. Results can vary by 100% or more!) I agree with double/triple/quadruple checking, taking a conservative approach, and staying flexible with a dose of humility in retirement.
Python & Programming Projects for $10 - $30. As a part of study, I have written Retirement Calculator using Monte Carlo Simulation. Multi-State Plan Program; Tribal Employers. With this online calculator you can rapidly and. See how the life insurance carried into retirement will change.
For this program, we would like the user to input two numbers, so let’s have the program prompt for two numbers. When asking for input, we should include a space at the end of our string so that there is a space between the user’s input and the prompting string.
I am not interested in stock marked monte carlo etc. As if you have won the game by having enough assets, there is no real gain in taking much chance of losing. As to inflation, there are other views on inflation than using the stock market. A 95% confidence in a monte carlo is very bad if you assume running out of assets is a disaster. If you applied 95% to air travel crashes for an analogy, you would have crashed in 20 flights. Those odds are too poor for me. Even 99% is one crash in 100 flights.
It stores a value into a variable to be used later on. The code below will assign 10 to the variable x, and then print the value stored in x. Look at the example below. Click on the “Step” button to see how the code operates.
OutputEnter your first number: 5 Enter your second number: 7 If you run this program a few times and vary your input, you’ll notice that you can enter whatever you want when prompted, including words, symbols, whitespace, or just the enter key. This is because input() takes data in as and doesn’t know that we are looking for a number. We would like to use a number in this program for 2 reasons: 1) to enable the program to perform mathematical calculations, and 2) to validate that the user’s input is a numerical string. Depending on our needs of the calculator, we may want to convert the string that comes in from the input() function to either an integer or a float. For us, whole numbers suit our purpose, so we’ll wrap the input() function in the int() function to the input to the. OutputEnter your first number: sammy Traceback (most recent call last): File 'testing.py', line 1, in number_1 = int(input('Enter your first number: ')) ValueError: invalid literal for int() with base 10: 'sammy' So far, we have set up two variables to store user input in the form of integer data types.

User-defined functions add(), subtract(), multiply() and divide() evaluate respective operations.
This program would be even more useful if it would interact with the user and ask the user for the miles driven and gallons used. This can be done with the input statement. See the code below: # This code almost works miles_driven = input('Enter miles driven:') gallons_used = input('Enter gallons used:') mpg = miles_driven / gallons_used print('Miles per gallon:', mpg) Running this program will ask the user for miles and gallons, but it generates a strange error as shown in Figure. Figure 1.4: Error running MPG program The reason for this error can be demonstrated by changing the program a bit: miles_driven = input('Enter miles driven:') gallons_used = input('Enter gallons used:') x = miles_driven + gallons_used print('Sum of m + g:', x) Running the program above results in the output shown in Figure.
An expression is anything that evaluates to a value. Examine the code below.
This tutorial presents a learning exercise to help you make a simple command-line calculator program in Python 3. While we’ll go through one possibile way to make this program, there are many opportunities to improve the code and create a more robust calculator. We’ll be using,,,, and handle user input to make our calculator. Prerequisites For this tutorial, you should have Python 3 installed on your local computer and have a programming environment set up on the machine. If you need to either install Python or set up the environment, you can do so by following the. Step 1 — Prompt users for input Calculators work best when a human provides equations for the computer to solve. We’ll start writing our program at the point where the human enters the numbers that they would like the computer to work with.
Is Your Retirement On Track? - Earn Double Points The AARP Retirement Calculator can provide you with a personalized snapshot of what your financial future might look like. Simply answer a few questions about your household status, salary and retirement savings, such as an IRA or 401(k). You can include information about supplemental retirement income (such as a pension or Social Security), consider how long you intend to work and think about your expected lifestyle as a retiree. The tool will help you determine the amount of money you’ll need to retire when – and how – you want.
Darrow, I think the Fidelity Retirement Income Planner uses Monte Carlo simulation to arrive at an average historical growth rate usually around 8%. I question that MC simulation of the entire market since 1929 would give an accurate average result for the type of market we have today.

(Offer Code: 220) **Before rolling over a 401(k) to an IRA, be sure to consider your other choices, including keeping it the former employer’s plan, rolling it into a 401(k) at a new employer, or cashing out the account value keeping in mind that taking a lump sum distribution can have adverse tax consequences. Whatever you decide to do be sure to consult with your tax advisor.
Any help would be greatly appreciated. My code is below: def main(): # Number of years left until retirement while True: try: years_left = int(input('Please enter the number of years left until retirement (1-70): ')) except ValueError: print ('Entered value is not a number! Please enter a number 1-70.' ) except KeyboardInterrupt: print('Command Error! Please enter a number 1-70.' ) else: if 1 10: confirm = input('Entered interest rate is greater than 10%.
Another example of good versus bad variable naming: # Hard to understand ir = 0.12 b = 12123.34 i = ir * b # Easy to understand interest_rate = 0.12 account_balance = 12123.34 interest_amount = interest_rate * account_balance Video: Creating a custom calculator program In the IDLE editor it is possible to edit a prior line without retyping it. Do this by moving the cursor to that line and hitting the “enter” key. It will be copied to the current line. Entering Python code at the >>> prompt is slow and can only be done one line at a time. It is also not possible to save the code so that another person can run it. Thankfully, there is an even better way to enter Python code.
) print('Hi') # This is an end-of-line comment It is possible to comment out multiple lines of code using three single quotes in a row to the comments. Print('Hi') '' This is a multi line comment. Nothing Will run in between these quotes. Print('There') '' print('Done') Most professional Python programmers will only use this type of multi-line comment for something called docstrings.
Does a comma go inside or outside the quotes? This next code example doesn't work at all. This is because there is no comma separating the text between the quotes, and the 1030+10. At first, it may appear that there is a comma, but the comma is inside the quotes. The comma that separates the terms to be printed must be outside the quotes. If the programmer wants a comma to be printed, then it must be inside the quotes: print('Your new score is,' 1030 + 10) This next example does work, because there is a comma separating the terms.
Would it be better to use the last 10 or 20 years only? And then cut it in half to not over estimate future growth. What do you think? I use a brute force spreadsheet approach that models each year of retirement (expenses and income) and I run a zero growth scenario just to be sure I don’t run out of money. From the zero growth case one can ballpark how much of a market deflation one can absorb. I think this is important. Thanks for sharing your research and knowledge.
Enter miles driven: 288 Enter gallons used: 15 Miles per gallon: 19.2 And another example, calculating the kinetic energy of an object: # Sample Python/Pygame Programs # Simpson College Computer Science # # # Calculate Kinetic Energy print('This program calculates the kinetic energy of a moving object.' ) m_string = input('Enter the object's mass in kilograms: ') m = float(m_string) v_string = input('Enter the object's speed in meters per second: ') v = float(v_string) e = 0.5 * m * v * v print('The object has ' + str(e) + ' joules of energy.' ) To shorten a program, it is possible to nest the input statement into the float statement. For example these lines of code: milesDriven = input('Enter miles driven:') milesDriven = float(milesDriven) Perform the same as this line: milesDriven = float(input('Enter miles driven:')) In this case, the output of the input function is directly fed into the float function.
