Python中一个function参数名称与另一个function相同的问题如何处理？

Question

Here is an example:

def clean_datetime(x):
    return x

def func(clean_datetime = True):
    if clean_datetime:
        return clean_datetime(1)
        
func(True)

This will return an error TypeError: 'bool' object is not callable . Is there a way I don't need to change the function parameter name?

Answer 1

Technically, you could pull the function out of globals() , but this is a terrible, terrible thing to do compared to just renaming the function or the parameter.

In [53]: def clean_datetime(x):
    ...:     return x
    ...:
    ...: def func(clean_datetime = True):
    ...:     if clean_datetime:
    ...:         return globals()['clean_datetime'](1)
    ...:
    ...: func(True)
Out[53]: 1

Answer 2

Like already suggested in the comments changing the function name or parameter name is a better option IMO. It makes the code less ambiguous.

A workaround is to create an alias for the function or create a function that calls the necessary function.

def clean_datetime(x):
    return x

alias = clean_datetime

def func(clean_datetime = True):
    if clean_datetime:
        return alias(1) # Calls clean_datetime(1)
        
func(True) # Returns 1

Answer 3

there is the only one way: you need to change the function name or parameter name
