Python nested for | Example code

The for loop is used to iterate over a sequence such as a list, string, tuple, or other iterable objects such as range. Using a for loop inside a for a loop is called a Python nested for.

for x in sequence:

  for y in sequence:

The outer loop can contain more than one inner loop without limitation on the chaining of loops.

Python nested for example

for i in range(0, 5):

    for j in range(0, 5):
        print(i * j, end=' ')
    print()

Output:

rows = 5
# outer loop
for i in range(1, rows + 1):
    # inner loop
    for j in range(1, i + 1):
        print("*", end=" ")
    print('')

Output:
