Escape Sequencing in Python

While printing Strings with single and double quotes in it causes SyntaxError because String already contains Single and Double Quotes and hence cannot be printed with the use of either of these. Hence, to print such a String either Triple Quotes are used or Escape sequences are used to print Strings. 

Escape sequences start with a backslash and can be interpreted differently. If single quotes are used to represent a string, then all the single quotes present in the string must be escaped and the same is done for Double Quotes.

Python 
# Initial String
String1 = '''I'm a "Geek"'''
print("Initial String with use of Triple Quotes: ")
print(String1)

# Escaping Single Quote
String1 = 'I\'m a "Geek"'
print("\nEscaping Single Quote: ")
print(String1)

# Escaping Double Quotes
String1 = "I'm a \"Geek\""
print("\nEscaping Double Quotes: ")
print(String1)

# Printing Paths with the
# use of Escape Sequences
String1 = "C:\\Python\\Geeks\\"
print("\nEscaping Backslashes: ")
print(String1)

# Printing Paths with the
# use of Tab
String1 = "Hi\tGeeks"
print("\nTab: ")
print(String1)

# Printing Paths with the
# use of New Line
String1 = "Python\nGeeks"
print("\nNew Line: ")
print(String1)

Output:

Initial String with use of Triple Quotes: 
I'm a "Geek"
Escaping Single Quote: 
I'm a "Geek"
Escaping Double Quotes: 
I'm a "Geek"
Escaping Backslashes: 
C:\Python\Geeks\
Tab: 
Hi    Geeks
New Line: 
Python
Geeks

Example:

To ignore the escape sequences in a String, r or R is used, this implies that the string is a raw string and escape sequences inside it are to be ignored.

Python 
# Printing hello in octal
String1 = "\110\145\154\154\157"
print("\nPrinting in Octal with the use of Escape Sequences: ")
print(String1)

# Using raw String to
# ignore Escape Sequences
String1 = r"This is \110\145\154\154\157"
print("\nPrinting Raw String in Octal Format: ")
print(String1)

# Printing Geeks in HEX
String1 = "This is \x47\x65\x65\x6b\x73 in \x48\x45\x58"
print("\nPrinting in HEX with the use of Escape Sequences: ")
print(String1)

# Using raw String to
# ignore Escape Sequences
String1 = r"This is \x47\x65\x65\x6b\x73 in \x48\x45\x58"
print("\nPrinting Raw String in HEX Format: ")
print(String1)

Output:

Printing in Octal with the use of Escape Sequences: 
Hello
Printing Raw String in Octal Format: 
This is \110\145\154\154\157
Printing in HEX with the use of Escape Sequences: 
This is Geeks in HEX
Printing Raw String in HEX Format: 
This is \x47\x65\x65\x6b\x73 in \x48\x45\x58

Python String

A String is a data structure in Python Programming that represents a sequence of characters. It is an immutable data type, meaning that once you have created a string, you cannot change it. Python String are used widely in many different applications, such as storing and manipulating text data, representing names, addresses, and other types of data that can be represented as text.

What is a String in Python?

Python Programming does not have a character data type, a single character is simply a string with a length of 1. Let’s see the Python string syntax:...

Accessing characters in Python String

In Python Programming tutorials, individual characters of a String can be accessed by using the method of Indexing. Indexing allows negative address references to access characters from the back of the String, e.g. -1 refers to the last character, -2 refers to the second last character, and so on....

String Slicing Python

In Python Programming tutorials, the String Slicing method is used to access a range of characters in the String. Slicing in a String is done by using a Slicing operator, i.e., a colon (:).  One thing to keep in mind while using this method is that the string returned after slicing includes the character at the start index but not the character at the last index....

Python String Reversed

Deleting/Updating from a String

In Python, the Updation or deletion of characters from a String is not allowed. This will cause an error because item assignment or item deletion from a String is not supported. Although deletion of the entire String is possible with the use of a built-in del keyword. This is because Strings are immutable, hence elements of a String cannot be changed once assigned. Only new strings can be reassigned to the same name....
