Python Strings encode() method

06 Jul, 2022
In today’s world, security holds the key in many applications. Thus the need for secure storage of passwords in the database is required and hence there is to save encoded versions of strings. To achieve this, python in its language has defined “encode()” that encodes strings with the specified encoding scheme. There are several encoding schemes defined in the language. The Python string encode() method encodes the string, using the specified encoding. If no encoding is specified, UTF-8 will be used.
Syntax:
encode(encoding, error)
Parameters: 
encoding: Specifies the encoding on the basis of which encoding has to be performed. 
error: Decides how to handle the errors if they occur, e.g ‘strict’ raises Unicode error in case of exception and ‘ignore’ ignores the errors that occurred. There are six types of error responsestrict – default response which raises a UnicodeDecodeError exception on failureignore – ignores the unencodable unicode from the resultreplace – replaces the unencodable unicode to a question mark ?xmlcharrefreplace – inserts XML character reference instead of unencodable unicodebackslashreplace – inserts a \uNNNN escape sequence instead of unencodable unicodenamereplace – inserts a \N{...} escape sequence instead of unencodable unicode
strict – default response which raises a UnicodeDecodeError exception on failure
ignore – ignores the unencodable unicode from the result
replace – replaces the unencodable unicode to a question mark ?
xmlcharrefreplace – inserts XML character reference instead of unencodable unicode
backslashreplace – inserts a \uNNNN escape sequence instead of unencodable unicode
namereplace – inserts a \N{...} escape sequence instead of unencodable unicode
Returns: 
Returns the string in the encoded form

Output: 
The available encodings are :
