Zip Function In Python

Map function is used to combine two or more iterables in a single iterable ( Map functions returns a Tuple). 

To illustrate its use, let take an example:

# define two lists
name = ['Lee','Shin','Chan']
roll = ['1','2','3']
name_n_roll = zip(name,roll)
print (name_n_roll)

Output:

[('Lee', '1'), ('Shin', '2'), ('Chan', '3')]

To unzip the zipped iterable we just have to use ” * ” while using zip. For Example:

name, roll = zip(*name_n_roll)

print(n,r)

Output:

((‘Lee’, ‘Shin’, ‘Chan’), (‘1’, ‘2’, ‘3’))
