Writing Raw String Literals for Escaped Characters in Python

Python strings can be tricky to write when you need to include special characters like backslashes, newlines, and tabs. To avoid having to manually escape these characters, Python provides raw string literals.

Raw string literals are denoted by an 'r' character before the opening quote of the string. This tells Python to interpret the string literally, without any special character handling.

For example, the following string contains a backslash, a newline, and a tab character:

my_string = "abc\dev\t"

If we print this string, we will see that the backslash, newline, and tab characters are interpreted literally:

print(my_string)

# Output: abc\dev\t

To avoid this, we can use a raw string literal:

my_string = r"abc\dev\t"

Now, when we print the string, the backslash, newline, and tab characters are printed as they are, without any special interpretation:

print(my_string)

# Output: abc\dev\t

Raw string literals are especially useful when dealing with very large strings that may contain many special characters. They simplify the task of writing and maintaining strings, ensuring that all characters are treated literally.
