Learn About Strings in Python

Introduction

 

In this article, I will explain strings in Python.

 

Definition

 

In Python, string data type is used to print a string statement in the output screen. We use symbol single quotations (or) double quotations to give the same result.

(“c# corner” is the same as ‘c# corner’).

 

Example

print("c# corner")#double quotation
print('c# corner')#single quotation

Output

 

 

Assign String Variables

 

In Python, to assign string variables, we use any alphabetic sentence(or) alphabet. The variable name is followed by an equal symbol and the string. (a=” welcome”)

 

Example

a=("welcome,'c# corner'")#double quotation and single quotation
print(a)#To print the output screen (a) assigned string variables.

Output

 

 

Multiline strings

 

In Python, we can assign one more lines to a variable. We use three quotes as the symbol. (“”’ some statement “””)

 

Example

a = '''''Great Wall of China.. ...
Christ the Redeemer in Rio de Janeiro ...
Machu Picchu in Peru. ...
Chichen Itza. ...
Roman Colosseum. ...
Taj Mahal in India. ...
Petra in Jordan.'''
print(a)

Output

 

 

String in array

 

Arrays are popular in most programming languages, such as Java or C/C++. An array is a separate string value, one by one. The first array is in the “0” position, the last array position is the negative value keyword (-1).

 

Example

a = "welcome,c# corner" #First array is the “0” position
print(a[1])# "1" array position is the second position.
print(a[-1])#last position
print(a[2:5])#position 2 to position 5.

Output

 

 

String length method

 

In python, the len () keyword is used to find many letters present in a string.

 

Example

a = "c# corner"
print(len(a))# find many letters present in string

Output

 

 

String lower method

 

In Python, the lower () keyword is used to change the string to lowercase.

 

Example

a = "c# corner"
print(a.upper())#change the string in upper case

Output

 

 

String Upper Method

 

In Python, the upper () keyword is used to change the string to upper case.

 

Example

a = "C# CORNER"
print(a.lower())#change the string in lower case

Output
