Python Strings (JNNC Technologies)

A string is usually a bit of text in programming that is written to be displayed to users. It is known to Python when you want to display a string. This is because programmers use either double quote “ or single quote ‘ to enclose a word or group of words to express a string.

Example:

#!/usr/bin/python

ch = 'HelloPython'

str1 = "String Chapter"

Accessing String Values

Characters are not supported by Python which makes it simpler as characters in Python are treated as strings of length 1 and hence considered as a sub-string.

Program showing the use of strings and how they are displayed on-screen.

Example:

#!/usr/bin/python

ch = 'Hello Python'

str1 = "String Chapter"

print ("First value is: " ,  ch)

print ("Second value is: " ,  str1)

Output:

First value is: Hello Python
Second value is: String Chapter

If they are considered as a list of characters, then the example shown below will let you understand how they are treated individually:

Example:

#!/usr/bin/python

ch = "Hello Python"

str1 = "String Chapter"

print ("First single sub-string is: " ,  ch[0])

print ("Set of sub-string is: " ,  str1[2:6])

Output:

First single sub-string is: H
Set of sub-string is: ring C
