Python Escape Characters

An escape sequence is considered as a sequence of characters that is used inside the character or string. It is further converted into a character or series of characters. Read this article to learn more about Python Escape Character.

What is an Escape Character in Python?

A sequence is a set of two or more characters. Whereas, in Escape, the sequence will begin with the backlash(//) and other characters in the set follow that backlash.

However, an escape sequence is referred to as the sequence of characters that are used inside the character or string. It won’t represent itself whereas it will be turned into another character. Hence, the escape sequence will be created with two things: first is a backlash (\\) and the second refers to the set of one or more characters with the backlash(\\).

What is the List of Escape Sequences in Python?

Escape characters will be divided into non-printable characters when the backlash precedes them.

The list of Escape sequences in Python is given below:

Code	Description
\’	Single quotation
\n	New Line
\\	Backlash
\t	Tab
\r	Carriage return
\b	Backspace
\f	Form feed
\xhhh	Hexadecimal equivalent
\ooo	Octal equivalent

What are the examples used to illustrate Escape single quotes in Python?

Using the single quote inside the string directly, thus the string will be closed inside the pair of single quotes. Hence, the interpreter will get confused and will produce an error output.

original_string = "This is a string with a single quote: 'Hello World'"
escaped_string = original_string.replace("'", "\\'")

print("Original String:", original_string)
print("Escaped String:", escaped_string)

In the example above, the replace method is used to replace each occurrence of a single quote (‘) with the escaped sequence (‘\\’).

Output

Original String: This is a string with a single quote: 'Hello World'
Escaped String: This is a string with a single quote: \'Hello World\'

What is an n Escape Sequence in Python?

”\n” tells the interpreter to print some characters in the new line separately. Check out the example given below:

def generate_sequence(n):
    sequence = [i for i in range(1, n + 1)]
    return sequence

# Replace '10' with your desired value of n
n = 10
result_sequence = generate_sequence(n)

print(f"The sequence up to {n} is: {result_sequence}")

Output

The sequence up to 10 is: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

What is the Backlash Escape Sequence in Python?

The character that consists of the backlash (\) method that is followed by the letter or by the combination of digits are known as escape sequences.

Check out this example given below:

escaped_string = "This is a backslash: \\"
print(escaped_string)

Output

This is a backslash: \

What is the Python escape sequence for Space?

This Python escape sequence for space will allow us to add tab space between the words. Hence, this escape sequence will provide the tab space between the words of characters using the ”\t”.

Example

# Using \s escape sequence
escaped_string = "Hello\sWorld"
print(escaped_string)

# Using space character directly
space_string = "Hello World"
print(space_string)

Output

Hello World
Hello World

What is the Backspace Escape Sequence in Python?

The escape sequence will help to remove the space between the words. Check out the example given below

# Using \b escape sequence
escaped_string = "Hello\bWorld"
print(escaped_string)

# Without escape sequence
normal_string = "Hello\bWorld"
print(normal_string)

Output

HelloWorld
HelloWorld

What is the Python escape sequence for Hexa value?

We will use ”\xhh”, where the hh is referred to as the unique Hexa value of the alphabet

Example

# Using \xhh escape sequence
hex_value = "\x48\x65\x6C\x6C\x6F"
print("String with hex values:", hex_value)

# Converting hex values to characters
decoded_string = bytes.fromhex(hex_value[2:]).decode('utf-8')
print("Decoded String:", decoded_string)

Output

String with hex values: Hello
Decoded String: Hello

What is the Python escape sequence for Octal value?

In Python escape sequence for an octal value, they use ”\ooo” and the ooo is the unique octal value of the alphabet.

Example

# Using \ooo escape sequence
octal_value = "\110\145\154\154\157"
print("String with octal values:", octal_value)

# Converting octal values to characters
decoded_string = bytes.fromhex(octal_value[1:]).decode('utf-8')
print("Decoded String:", decoded_string)

Output

String with octal values: Hello
Decoded String: Hello

How to remove the Python escape sequence?

Python escape sequence will be removed from the left to right of the argument string. Hence, it will use the string. strip () function.

def remove_escape_sequences(input_string):
    # Encode the string to bytes and then decode it
    decoded_string = input_string.encode('utf-8').decode('unicode_escape')
    return decoded_string

# Example usage
original_string = "This is a string with escape sequences: \\n\\t\\'"
removed_escape_string = remove_escape_sequences(original_string)

print("Original String:", original_string)
print("String with Escape Sequences Removed:", removed_escape_string)

Output

Original String: This is a string with escape sequences: \n\t\'
String with Escape Sequences Removed: This is a string with escape sequences: \n	'

Conclusion

Escape characters help manage the formatting and representation of special characters within strings, enabling more flexible and readable code. This article will allow the students to improve their knowledge and skills of the escape characters. It has also provided a list of the escape sequences in Python.
