0Zip() in Python
Zip() in Python
With the zip() method in Python, you may build an iterator that combines elements from multiple iterables. The resultant iterator can be used to efficiently and reliably address typical programming issues, such as building dictionaries.
Python Zip()
In Python, zip() is a built-in function that is used for combining multiple iterables (such as lists or tuples) into a single iterable. It pairs elements from each input iterable based on their respective positions, creating tuples of elements.
Syntax :
zip(iterable1, iterable2, ...)
iterable1, iterable2 and so on are the input iterables that you want to combine.
The iterator that zip() returns creates tuples with elements from the input iterables. When the shortest input iterable is exhausted, the resulting iterator comes to an end. This means that zip() will only combine elements up to the length of the shortest iterable if the input iterables have different lengths.
Code 1:
l1 = [1, 2, 3]
l2 = ['a', 'b', 'c']
zip_list = zip(l1, l2)
for i in zip_list:
print(i)
Output :
(1, 'a')
(2, 'b')
(3, 'c')
We can easily unpack the tuple if needed and combine more than 2 iterables. Let’s understand it with an example:
Code 2 :
l1 = [1, 2, 3]
l2 = ['a', 'b', 'c']
l3 = [10, 20, 30]
zip_list = zip(l1, l2, l3)
for i in zip_list:
a, b, c = i
print(a, b, c)
Output :
1 a 10
2 b 20
3 c 30
