python how to unnest a nested list
# Basic syntax:
unnested_list = list(chain(*nested_list))
# Where chain comes from the itertools package and is useful for
# unnesting any iterables
# Example usage:
from itertools import chain
nested_list = [[1,2], [3,4]]
my_unnested_list = list(chain(*nested_list))
print(my_unnested_list)
--> [1, 2, 3, 4]nested loop in list comprehension
# 2-D List
matrix = [[1, 2, 3], [4, 5], [6, 7, 8, 9]]
# Nested List Comprehension to flatten a given 2-D matrix
flatten_matrix = [val for sublist in matrix for val in sublist]
print(flatten_matrix)python nested list
L = [[1, 2, 3],[4, 5, 6],[7, 8, 9]]
for list in L:
for number in list:
print(number, end=' ')
# Prints 1 2 3 4 5 6 7 8 9Copyright © 2021 Codeinu
