itertools module in python code example

Example 1: 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?"

Example 2: itertools.zip_longest fill value

from itertools import zip_longest

chars = []
correct = 'hangman'
guess = 'winger'
for c, g in zip_longest(correct, guess, fillvalue='_'):
    if c == g:
        chars.append(c)
    else:
        chars.append('_')

print(chars)
# ['_', '_', 'n', 'g', '_', '_', '_']

word = ''.join(chars)
print(word)
# __ng___
