python itertools repeat()

# How to use it:
# repeat(var, amount)

# repeat() is basically like range() but it gives an extra arg for a var

from itertools import repeat

for x in repeat("Spam? Or Eggs?", 3):
    print(x)
> "Spam? Or Eggs?"
> "Spam? Or Eggs?"
> "Spam? Or Eggs?"

# itertools.takewhile(predicate, iterable)
# Make an iterator that returns elements from the iterable 
# as long as the predicate is true. Roughly equivalent to:

def takewhile(predicate, iterable):
    # takewhile(lambda x: x<5, [1,4,6,4,1]) --> 1 4
    for x in iterable:
        if predicate(x):
            yield x
        else:
            break
