Write three lines of code, each with a different error. Then, explain how to fix each one.

Question

Is there an error in this program? If so, what is it, what type is it, and how would you fix it?

def sum(num1, num2):
return num1 + num2

print(sum("four", "five"))

What is wrong with this program, which will be part of an exercise app, and how would you fix it?

print("Next, we'll do four push-ups.")

for i in range(4):
print("Do push-up #", i)

Describe five items that you would put into a software requirements specification if you were hiring someone to design an app to help museum visitors have a better experience.
Identify five errors in this program, which is supposed to take the average mean
of three numbers:

define average(one, two, three):
avg = one + two * three
return aver

GPT-4o mini · Answer

Here are three lines of code, each with a different error, along with explanations on how to fix them:

Code and Errors

Code:
```
def sum(num1, num2):
return num1 + num2
```
Error: IndentationError - the return statement is not properly indented inside the sum function.

Fix: Make sure the return statement is indented properly to match the function definition.
```
def sum(num1, num2):
    return num1 + num2
```
Code:
```
print(sum("four", "five"))
```
Error: TypeError - the sum function tries to add two strings which is not intended for numerical addition.

Fix: Change the strings to integers or handle the input appropriately. If you want to add the numeric values:
```
print(sum(4, 5))
```
Code:
```
for i in range(4):
print("Do push-up #", i)
```
Error: IndentationError - the body of the for loop is not properly indented.

Fix: Indent the print statement to be inside the for loop:
```
for i in range(4):
    print("Do push-up #", i)
```

Explanation of Program

The initial program contains errors that can lead to runtime exceptions or unexpected behavior. After fixing the indentation for the sum function and the for loop, you should also ensure the types of input make sense.

Key Problems and Fixes

Function Declaration Error:
```
define average(one, two, three):
```
Error: SyntaxError - define should be def.

Fix:
```
def average(one, two, three):
```
Calculation Error:
```
avg = one + two * three
```
Error: This does not calculate the average correctly as it uses multiplication instead of addition. The formula for average should sum all numbers and divide by their count.

Fix:
```
avg = (one + two + three) / 3
```
Return Variable Name Error:
```
return aver
```
Error: There is a typo in the return variable. It should return avg, not aver.

Fix:
```
return avg
```
Print Statement Mismatch:
```
print("The average of 6, 7, and 8 is: ," average(6, 7, 8))
```
Error: There is a misplaced comma; the correct syntax for calling the function and passing it in a print function needs parentheses without a comma.

Fix:
```
print("The average of 6, 7, and 8 is:", average(6, 7, 8))
```
Incorrect Calculation Without Parentheses Error: No parentheses were used in the sum calculation; this could lead to unintended operator precedence.
