Traversing a String

Sammarth Kumar

Traversing means accessing the characters of a string. We can do so using a for loop or a while loop.

Traversing using for:

1
2
3

string = "Q-Programming"
for character in string:
    print(character)

Q
-
P
r
o
g
r
a
m
m
i
n
g

Traversing using while:

1
2
3
4
5

string = "Q-Programming"
index = 0
while index < len(string):
    print(string[index])
    index += 1

Q
-
P
r
o
g
r
a
m
m
i
n
g

Here we used len() to get the total number of characters in the string. The while loop will access all the characters of the string from index 0 to index len(string) -1 , which is all the characters of the string.
