What is escape character in python with example?
What is escape sequence?
The sequence of character which has indirect meaning when it placed within double quotes.
It will optimize some the repetitive tasks while programming.
While printing some statement, if you want to give horizontal tab (usually four spaces) in between every word like below,
#escape sequence example print("Happy New Year")
Here, we manually gave four space between each word. This can be achieved easily with \t escape sequence.
#escape sequence in python print("Happy\tNew\tYear")

Escape characters or sequences are illegal characters for Python and never get printed as part of the output. When backslash is used in Python programming, it allows the program to escape the next characters.
Following would be the syntax for an escape sequence
Here, the escape character could be t, n, e, or backslash itself.
Types of Escape Sequence
Escape characters can be classified as non-printable characters when backslash precedes them. The print statements do not print escape characters.

Example Usage of Various Escape Characters
What Does “\t” Do in Python?
The t alphabet in Python represents a space. It enables you to insert space or tab between strings in a code. It helps us to have space in the Python program when there is a need for it. To eliminate the usage of keyboard space, the coders utilize tab escape sequences.
Following is the syntax for a tab escape sequence.
In this example, the string used is “Guru99”. The program will put a tab or a space between Guru and 99.
TextExample="Guru\t99" print (TextExample)
In the above example, instead of adding space using a keyboard, the program helps us by putting a space or a tab between the string “Guru99”. It also provides a space at the precise location where the escape sequence is added.
When to use “\t” in Python?
The escape sequence tab is utilized to put a horizontal tab between words and hence helps manipulate python strings. However, If the escape sequence tab is not used, the programmer has to manually add a space between every word of the string.
You can transform it into a time-consuming exercise. Moreover, the space added between different keywords may or may not be precise in its placement.
Here is an example that displays the manual addition of a space between words and the use of an escape sequence between words.
print("Manually Added space in string Guru 99") TextExample="Use\tof\ttab\tto\tadd\tspace\tGuru\t99" print(TextExample)
Manually Added space in string Guru 99 Use of tab to add space Guru 99
The programmer manually added space between words in the above code, so the placement was not precise. When the escape sequence tab was applied, the program automatically provided the precise location of space between words.
Application of built-in function Chr () and Ord ()
The Chr () function is a built function that takes a single argument as input. The function takes Unicode characters as an input which ranges from 0 to 1,114 and 111, respectively. The function can be used as the substitute for escape sequence “\t” to put a space between two words.
The syntax for the Chr function is represented below: –
The tab has the Unicode character 9. Use the following Python command to arrive at the Unicode character as shown below: –
print("Unicode character of the tab is") Ord=ord('\t') print(Ord)
Unicode character of the tab is 9
The above code provides the Unicode character for the tab. It can be used as an input for the Chr function. Use of Chr (9) would allow us to create a substitute for a tab escape sequence.
This code is an example of how to use Chr (9), as shown below:
The above function, however, is deprecated for version 3 and above.
What is an escape character give an example?
An escape sequence in C language is a sequence of characters that doesn't represent itself when used inside string literal or character. It is composed of two or more characters starting with backslash \. For example: \n represents new line.

What is escape character?
\r is a carriage return character; it tells your terminal emulator to move the cursor at the start of the line. The cursor is the position where the next characters will be rendered. So, printing a \r allows to override the current line of the terminal emulator.
Does Python have escape characters?
In Python strings, the backslash "\" is a special character, also called the "escape" character. It is used in representing certain whitespace characters: "\t" is a tab, "\n" is a newline, and "\r" is a carriage return.
