Python String Slicing Explained with Examples

A range of characters can be returned using the slice syntax. Specify the start and end indexes, separated by a colon, to retrieve a part of the text.

Example:

b = "Hello WSC"

print(b[2:5])

Output

The range will begin with the first character if the start index is omitted:

Example:

b = "Hello WSC"

print(b[:5])

Output

The range will go to the end if the end index is omitted.

Example:

Get the characters from position 2, and all the way to the end:

b = "Hello WSC"

print(b[2:])

Output

To begin the slice from the end of the string, use negative indexes:

Example

b = "Hello, World"

print(b[-5:-1])

Output

Example

b = "Hello, World"

print(b[0:5:2])

Output

The keyword can be used to see if a phrase or character is contained in a string.

Code:

text = "Welcome to wscube tech"

print("tech” in text)

Output:

It is possible to cycle over a string using a For loop. This is an example of how to count the number of 'l's in a string.

Example:

count = 0

for letter in 'Hello World':

    if(letter == 'l'):

        count += 1

print(count,'letters found')

Output
