Answer 1

Basically the zip function works on lists, tuples and dictionaries in Python. If you are using IPython then just type zip? And check what zip() is about.

If you are not using IPython then just install it: "pip install ipython"

For lists

a = ['a', 'b', 'c']
b = ['p', 'q', 'r']
zip(a, b)

The output is [('a', 'p'), ('b', 'q'), ('c', 'r')

For dictionary:

c = {'gaurav':'waghs', 'nilesh':'kashid', 'ramesh':'sawant', 'anu':'raje'}
d = {'amit':'wagh', 'swapnil':'dalavi', 'anish':'mane', 'raghu':'rokda'}
zip(c, d)

The output is:

[('gaurav', 'amit'),
 ('nilesh', 'swapnil'),
 ('ramesh', 'anish'),
 ('anu', 'raghu')]
