Coding an Addition Game in Python
- This instruction set will teach you step-by-step how to program an addition game that prompts users to answer simple addition problems using random numbers from 0-9 and prints whether they are correct or not!
- Click the image in each step to enlarge it and view the code for that part.
Launch Your Python Coding App.
- This instruction set will be using the IDLE Python program!
-
After launching, create a New File in your Python application to start coding.
Import the Random Class.
- We will be using it to generate random numbers!
Define a Python Method With an Input Variable N.
- The input of integer n will determine the number of addition problems the game will print when called!
- This code calls the method "game(n)".
Initialize a Boolean Variable and an Integer Variable.
- Within the game method, initialize a Boolean variable to be used in a ‘while’ loop and an integer to be used as a count variable for correct answers.
- This code calls the Boolean “wrk” and integer “cnt”.
- Remember the importance of indents in Python, as they determine what code is nested where!
Start a ‘for’ Loop for Range N.
- This will loop for the length of the input integer n!
Initialize Two Random Integer Values Between 1 and 10 and Set Boolean Value to True.
- Within this ‘for’ loop, use random.randrange(1,10) to initialize two random integer values between 1 and 9.
- This code calls these “val1” and “val2”.
- Then set the Boolean value to True!
Start a ‘while’ Loop While the Boolean Variable Is True.
- While still within the ‘for’ loop, start a ‘while’ loop while the Boolean variable is True.
Print an Addition Problem With Values 1 and 2 and Take the Answer As Input.
- Next in this ‘while’ loop, we create a try-except statement.
- In your ‘try’ case, print out an addition question using value 1 and value 2 and define an answer variable as the user’s input (this code defines the answer variable as “ans”).
Make an If-else Statement Testing Whether Answer = Value 1 + Value 2.
- Within the ‘try’ case, code an if-else statement testing whether ans = val1 + val2.
If True, Print a Correct Message, Set the Boolean Variable to False, and Increment Count.
- Still within the 'try' statement, if true:
- Print a correct message!
- Set the Boolean variable to False!
- Increment count by 1!
If Not, Print an Incorrect Message and Set the Boolean Value to False.
- In the 'else' statement, print an incorrect message and set the Boolean value to False.
Account for Non-integer Inputs With an Error Message.
- In the ‘except’ case, print an error message to account for non-integer inputs!
At the End of the Program, Print the Count of Problems Out of N That the Player Got Right.
- After all those nested statements, print the count of problems out of n that the player got right!
Look Over Your Code!
- Remember the importance of indentation in Python, as this program utilizes many nested statements.
- Your final program should look like this.
