Checking if conditions hold in boolean list

I'm trying to run some function if a list of booleans is true. My list consists of boolean functions.

list = [file.endswith('05',21,22), file.endswith('11',21,22),
       file.endswith('17',21,22), file.endswith('21',21,22),
       file.endswith('23',21,22)]

if any(True in list) == True:           
    # do something

Currently, the if clause gives me an error 

  if any(True in list) == True:
TypeError: 'bool' object is not iterable

Not really sure how to fix it.

Note that your code is much shorter if written as:

if any(file.endswith(suffix, 21, 22) 
       for suffix in ['05', '11', '17', '21', '23']):

any(iterable):

Return True if any element of the iterable is true. If the iterable is empty, return False.

Your code should use:

 if any(list):

any is expecting an iterable argument, which it will then run through to see if any of its items evaluate to True. Moreover, the expression True in list returns a non-iterable boolean value:

>>> lst = [False, True, False]
>>> True in lst
True
>>>

To fix the problem, you should simply pass the list to any:

if any(list):

You should also refrain from making a user-defined name the same as one of the built-ins. Doing so overshadows the built-in and makes it unusable in the current scope.
