Python Tutorial

A for loop is used for iterating over a sequence.

Sequence in python may be:

• list

• tuple

• dictionary

• set

• string

Print each number in a numbers list:

#list
numbers = [1, 2, 3, 4, 5, 6]
for number in numbers:
     print(number)

Output:

1
2
3
4
5
6

Even strings are iterable objects, they contain a sequence of characters:

for char in "Codersarts":
  print(char)

Output:

C
o
d
e
r
s
a
r
t
s

range() Function in Python

The range() function returns a sequence of numbers, starting from 0 by default, and increments by 1 (by default), and ends at a specified number.

for x in range(5):
  print(x)

Output:

0
1
2
