Is it Pythonic to use list comprehensions for just side effects?

Question

Think about a function that I\'m calling for its side effects, not return values (like printing to screen, updating GUI, printing to a file, etc.).

def fun_wi         


        

Answer 1

Second is better.

Think of the person who would need to understand your code. You can get bad karma easily with the first :)

You could go middle between the two by using filter(). Consider the example:

y=[1,2,3,4,5,6]
def func(x):
    print "call with %r"%x

for x in filter(lambda x: x>3, y):
    func(x)
