Python Strings
In this tutorial, you’ll learn to properly handle strings in python, print, slice, and format them. Python strings are a sequence of characters that occur one after the other forming a meaningful word or sentence.

Added new topics such as Escape Codes with some more examples.
You can create a string using single, double or triple quotes
str_one = "Say Hello to Python Programming"
print(str_one)
str_two = 'Say Hello to Python Programming'
print(str_two)
str_three = '''
Say Hello
to
Python Programming'''
print(str_three)
str_four = """
Say Hello
to
Python Programming"""
print(str_four)
#PYTHON OUTPUT
Say Hello to Python Programming
Say Hello to Python Programming
Say Hello
to
Python Programming
Say Hello
to
Python Programming
Python Strings – Creating string using single, double or triple quotes
Note
The triple quotes string are used for multiline text purpose.
Escape Codes
The Escape Codes are command and frequently used part of programming they are represented as with backslash followed by a character. Each of the escape characters has a specific purpose such as the \n is a newline character which prints upcoming character in a new line. Some of the Escape Codes are mentioned below:
| Symbol | Name | Description | Example |
|---|---|---|---|
| \n | New Line Feed | Prints upcoming string in a new line |
>>print("Hello\nWorld")
Hello
World
|
| \r | Carriage Return | This prints the next sequence of characters to the start off the line. |
>>print("Hello\rWorld")
World
|
| \t | Horizontal Tab | Horizontal Tab adds empty spaces from where it is mentioned. |
>>print("Hello\tWorld")
Hello World
|
| \v | Vertical Tab | Vertical Tab adds empty spaces from next to were it was mentioned. |
>>print("Hello\vWorld")
Hello
World
|
| \b | Backspace | Truncates a single character and works the same way as a keyboard backspace. |
>>print("Hello\bWorld")
HellWorld
|
| \f | Form Feed also called as Page Feed | Breaks the current page and continues to the next page and starts from the same position where is left. |
>>print("Hello\fW\forld")
Hello
W
orld
|
| \a | Alert | Produces beeps sound. |
>>print("Hello\aWorld")
HelloWorld
|
| \\ | Backslash | Escapes special characters like single and double-quotes. |
>>print('Hello it\'s me')
Hello it's me
|
a = 'This is a python string...from single qoutes' b = "This is a python string...from double qoutes" c = '''This is a python string...from 3 single qoutes on start and finish''' d = """This is a python string...from 3 double quotes on start and finish""" print(a) print(b) print(c) print(d) #Python output This is a python string...from single quotes This is a python string...from double quotes This is a python string...from 3 single quotes on start and finish This is a python string...from 3 double quotes on start and finish
Accessing String
Strings can also be accessed by index just like arrays.
Example
website_name = "TheCodeLearners" print(website_name) print(website_name[0]) print(website_name[1]) print(website_name[2]) print(website_name[3]) print(website_name[4]) print(website_name[5]) print(website_name[6]) print(website_name[7]) print(website_name[8]) print(website_name[9]) print(website_name[10]) print(website_name[11]) print(website_name[12]) print(website_name[13]) print(website_name[14]) #Python OUTPUT TheCodeLearners T h e C o d e L e a r n e r s
print(website_name[15]) #PYTHON ERROR OUTPUT string index out of range
Escape Special Characters in String
Backslash \ is used to escape any special character in the string.
Example
string = "This string with double quotes" e_string = "This string with \"double quotes escaped with a backslash" a_string = 'I don\'t like this' print(string) print(e_string) print(a_string) #PYTHON OUTPUT This string with double quotes This string with "double quotes escaped with a backslash I don't like this
Print string in new line use \n
Example
x = 'This will be printed in first line.\nThis will be printed in second line' print(x) #PYTHON OUTPUT This will be printed in first line. This will be printed in second line
Raw Strings
If for some cases you wanted to omit special character \ backslash then you can use raw strings by placing `r` at the start of the string
Example
string = 'Some File Path \temp\name\read' e_string = r'Some File Path \temp\name\read' print(string) print(e_string) #Python OUTPUT Some File Path emp ead Some File Path \temp\name\read
String Concatenation and Formatting
You can also concatenate strings with variables inside it.
age = 15
print("Jim is "+str(age)+" years old.")
#PYTHON OUTPUT
Jim is 15 years old.
age = 15
print("Jim is %d years old." % age)
#PYTHON OUTPUT
Jim is 15 years old.
age = 15
print("Jim is {} years old.".format(age))
#PYTHON OUTPUT
Jim is 15 years old.
age = 15
print("Jim is {new_age} years old.".format(new_age=age))
#PYTHON OUTPUT
Jim is 15 years old.
age = 15
print(f"Jim is {age} years old.")
#PYTHON OUTPUT
Jim is 15 years old.
