Why map(print, a_list) doesn't work?

Question

For a normal function, map works well:

def increment(n):
    return n+1
l = [1, 2, 3, 4, 5]
l = map(increment, l)
print l
>>> [2, 3, 4,         


        

Answer 1

Because print is not a function.

But you can make print-wrapper, of course:

>>> def p(x):
...   print x
... 
>>> l = [1, 2, 3, 4, 5]
>>> l = map(p, l)
