urllib quote_plus - Python

The quote_plus function in urllib module of Python is used to encode a string according to the application/x-www-form-urlencoded format. This format is commonly used to encode the data that is being passed through HTTP headers or in the URL query string.

Syntax:

urllib.parse.quote_plus(string, safe='', encoding=None, errors=None)

Parameters:

• string: The string that needs to be encoded.
• safe: Optional parameter that specifies the safe characters that should not be encoded. By default, it is set to '/' which is the character that separates different parts of a URL.
• encoding: Optional parameter that specifies the character encoding that should be used. By default, it is set to 'utf-8'.
• errors: Optional parameter that specifies the error handling scheme that should be used. By default, it is set to 'strict' which will raise an error if there is any problem encoding the string.

Return Value:

The quote_plus function returns a string that is encoded according to the application/x-www-form-urlencoded format.

Example:

import urllib.parse

text = "Hello, world!"
encoded_text = urllib.parse.quote_plus(text)

print("Original Text: ", text)
print("Encoded Text : ", encoded_text)

Output:

Original Text:  Hello, world!
Encoded Text :  Hello%2C+world%21

In the above example, we are using the quote_plus function to encode the text "Hello, world!". The encoded text is then printed to the console.

We can see that all the special characters in the text have been encoded using their corresponding ASCII values. The space character ' ' has been replaced with '+'.
