Explain Python's zip() function.?

Answer 1

The zip function will take a number of ordered collections that are the same length and creates an iterator that returns a merged version. The first element in each list returned together in a tuple. The same with each sequential element from all the lists. For example:

for x in zip([1, 2, 3], ['rock', 'paper', 'scissors']):

  print(x)

(1, 'rock')

(2, 'paper')

(3, 'scissors')
