Use two for loop or use zip() function to list comprehension two lists in Python. Here is the syntax of List Comprehension with two lists.
[ expression for x in list_1 for y in list_2 ]Example list comprehension two lists in Python
Simple example code List Comprehension with Two Lists and create a new list.
list_1 = [1, 2, 3]
list_2 = [5, 6]
list_3 = [x * y for x in list_1 for y in list_2]
print(list_3)
Output:
Another example using zip() method
Iterate two or more lists simultaneously within list comprehension.
list_1 = [1, 2, 3]
list_2 = [5, 6]
res = [(i, j) for i, j in zip(list_1, list_2)]
print(res)
Output: [(1, 5), (2, 6)]
Nested list comprehension with two lists
matrix = [[j for j in range(5)] for i in range(5)]
print(matrix)
Output:
[[0, 1, 2, 3, 4], [0, 1, 2, 3, 4], [0, 1, 2, 3, 4], [0, 1, 2, 3, 4], [0, 1, 2, 3, 4]]
