Question

Hello!

Working with python

This program asks user math questions and keeps track of answers...

1. Allow the user to decide whether or not to keep playing after each math challenge.

2. Ensure the user’s answer to each math problem is greater than or equal to zero.

3. Keep track of how many math problems have been asked and how many have been answered correctly.

4. When finished, inform the user how they did by displaying the total number of math problems, the number they answered correctly, and their percent correct.

Provide meaningful comments

I need for this code to allow user to enter a float as user result

and then round users result so it matches with actual rounded result

I need this done for add,sub,div, and mul

Answer 1

Solution:

Change below lines in each method, { add(), sub(), div(), mul() }

• Replace each user input line "users_result = int(input())" with "users_result = float(input())"
• Round off user result up to 2 decimal places, i.e, add line users_result = round(users_result, 2)
• Round off actual output up to 2 decimal places, i.e, result = round(result, 2)
• Now, float values entered by user are handled properly.

Updated code of div() function:

def div():
    global Answer_count
    import random
    a = random.randint(0,1000)
    b = random.randint(0,1000)
    
    result=a/b
    result = round(result, 2)                            # Updated code
    
    if result<0:
        div()
    else:
        print("Find ",a,"/",b,"and Enter your Answer")
        
        users_result=float(input())                      # Updated code
        users_result = round(users_result, 2)            # Updated code
        
        print("you typed: ", users_result)
        if(users_result<0):
            print("Result cannot be negative ! ! Do again")
            div()
        elif(users_result==result):
            print("Right Answer !!")
            Answer_count+=1
        else:
            print("Wrong Answer !! Right answer is ",result)

Input:

Enter your choice 

Menu
1.Addition
2.Substraction
3.Division
4.Multiplication
5.Exit

3

Find  74 / 841 and Enter your Answer:  0.0822
Wrong Answer !! Right answer is  0.09


Enter your choice 

Menu
1.Addition
2.Substraction
3.Division
4.Multiplication
5.Exit

5

Output:

Total Number of problems attended :  1
Right answers :  0
Percentage of Right answer :  0.0

Make similar changes to other methods as well.

PS: Let me know if you are able to make changes to the code. Ask if you have any doubt.
