Python Escape Characters Explained
In Python, an escape character is used to insert characters that are otherwise not allowed directly within a string. This technique is crucial when handling string data that includes special symbols, such as quotation marks or backslashes.
What Is an Escape Character?
An escape character in Python is a backslash (\) followed by a specific character. This combination tells the interpreter to treat the following character differently than usual.
Example: Handling Double Quotes
Consider the following incorrect string definition:
txt = "We are the so-called "Vikings" from the north."The code above will result in a syntax error because the double quotes used within the string conflict with the string delimiters. To solve this, use the escape character:
txt = "We are the so-called \"Vikings\" from the north."Now, Python understands that the inner quotation marks are part of the string, not the end of it.
Common Escape Characters in Python
Here is a table summarizing the most commonly used escape characters in Python:
| Code | Result |
|---|---|
\' |
Single Quote |
\\ |
Backslash |
\n |
New Line |
\r |
Carriage Return |
\t |
Tab |
\b |
Backspace |
\f |
Form Feed |
\ooo |
Octal value |
\xhh |
Hexadecimal value |
Each of these characters allows for more flexibility and control over how strings are structured and displayed in Python programs.
