Question

Is it permissible for a local variable in one function to have the same name as a local variable in a different function?

Short answer

Explain your answer. Answer: Yes, local variables can have the same name across different functions. This is because the scope of a local variable is limited to the function it is declared in. The variables in different functions have no effect on each other even if they have the same name. They exist within their respective functions, and their values are independent of one another.

Step-by-step solution

Understand local variables

Local variables are variables which are declared inside a function and can only be used within that function. Their names are only recognized within the scope of the function, which means that once the function ends, their values are forgotten.

Determine if local variables can share the same name across different functions

Yes, it is permissible for local variables in different functions to have the same name. As the variable scope is limited to the function it is declared in, the variables have no effect on each other.

Example with local variables having the same name

Consider the following two functions: Function A: ```python def function_A(): x = 5 print(x) ``` Function B: ```python def function_B(): x = 10 print(x) ``` In both functions, we have a local variable called "x". Despite having the same name, these variables only exist within their respective functions, and their scope is limited to that function. Therefore, the two "x" variables have their own values and do not cause any conflicts. If we execute these functions, we will get the following output: ```python function_A() # Output: 5 function_B() # Output: 10 ``` This demonstrates that the local variables with the same name in different functions have no impact on each other, and their scopes are limited to their respective functions.
