python nested list

# example of a nested list
my_list = [[1, 2], ["one", "two"]]

# accessing a nested list
my_list[1][0] # outputs "one"

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 9

Nested For Python list

Vowel=['a','e','i','o','u']
if 'e' in Vowel:
print('Present')
else:
print('absent')

List Nested Lists

x = [3, 4, [7, 8]]
print(x[2][1])
