If added to the program below, which of the following additional functions would not cause an error?
def subtract_nums():
z = x – y
print z
def subtract_nums():
z = z – x
print z
def subtract_nums():
y = 5
z = x – y
print z
def subtract_nums():
z = y
z = x – y
print z
To determine which of the additional functions would not cause an error, we need to check each function for variable definitions and scope.
1. First Function: `def subtract_nums(): z = x – y print z`
This will cause an error because `x` and `y` are not defined within the function.
2. Second Function: `def subtract_nums(): z = z – x print z`
This will also cause an error because `z` is not defined before it’s used.
3. Third Function: `def subtract_nums(): y = 5 z = x – y print z`
This function will cause an error because `x` is not defined.
4. Fourth Function: `def subtract_nums(): z = y z = x – y print z`
This will also cause an error because `y` is not defined before it’s used.
None of the provided functions will run without errors due to undefined variables. Therefore, there are no additional functions among the provided options that would not cause an error.
It’s important to ensure that all variables are defined before they are used within functions. If you have further questions or need more help with this topic, feel free to ask!
