Python’s zip() function

numbers = list(range(5)) # list of numbers 
letters = ['a', 'b', 'c', 'd', 'e'] # list of numbers
# Create an iterator object using zip()
zipped = zip(numbers, letters)
# Print the type of zipped
print('Type of zipped is: {}'.format(type(zipped)))
Type of zipped is: <class 'zip'>
# Create a list of tuples from zipped object
zipped_list = list(zipped)
# Print the list of tuples
print('List of tupples is: {}'.format(zipped_list))
List of tupples is: [(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd'), (4, 'e')]
for num, lett in zip(numbers, letters): 
print(num, lett)
0 a
1 b
2 c
3 d
4 e
pairs = [(0,'x'), (1, 'y'), (2, 'z')] # list of tupples# use unpacking operator * to unzip the data
nums, alphabets = zip(*pairs)
# Print the outputs
print(nums)
print(alphabets)
(0, 1, 2)
('x', 'y', 'z')
