Hello
    
    any() and all() are very useful small functions, and I am wondering     if it could be interesting to have them work 
    with different operators, by using a callable. 
    
    e.g. something like:
    
import operator
         
def any(iterable, filter=operator.truth):
    for element in iterable:
        if filter(element):
            return True
    return False
    
    For instance I could then us any() to find out if there's a None in     the sequence:
    
    
if any(iterable, op=lambda x: x is None):
    raise SomeError("There's a none in that list")
    
    Granted, it's easy to do it myself in a small util function - but     since any() and all() are in Python...
    
    
    Cheers

Hello

any() and all() are very useful small functions, and I am wondering if it could be interesting to have them work
with different operators, by using a callable.

e.g. something like:
  
import operator  

def any(iterable, filter=operator.truth):  
 for element in iterable:  
 if filter(element):  
 return True  
 return False

For instance I could then us any() to find out if there's a None in the sequence:

if any(iterable, op=lambda x: x is None):  
 raise SomeError("There's a none in that list")

Granted, it's easy to do it myself in a small util function - but since any() and all() are in Python...


Cheers
Tarek
