Security is crucial in a variety of applications. As a result, secure password storage in the database is required, and encoded copies of strings must be saved. Python’s language contains a method called encode() that encodes strings.
The encode() method encodes strings using the provided encoding scheme. The language specifies the number of encoding techniques.
UTF-8 will be used if no encoding is given.
The encode() method in Python returns a string that has been encoded.
string.encode(encoding=encoding, errors=errors)
encoding: Optional. It is a string specifying the encoding to use. The default is UTF-8.
errors: Optional. This is a string specifying the error method, meaning, how to handle errors if they occur. There are six types of error messages:
strict: This is the default response, which throws a UnicodeDecodeError exception if the decoding fails.replace: This substitutes the unencodable Unicode with a question mark.ignore: This ignores the unencodable Unicode from the result.xmlcharrefreplace: This replaces unencodable Unicode with an XML character reference.backslashreplace: Instead of unencodable Unicode, insert a \uNNNN escape sequence.namereplace: This replaces unencodable Unicode with an \N{…} escape sequence.The encode() method returns the encoded version of the string.
The following code shows how to use the encode() method in Python:
We make a program to list all the encoding available in Python.
# print all encodings availablefrom encodings.aliases import aliases# Printing list availableprint("The available encodings are : ")print(aliases.keys())
The code above displays all the available encoding schemes in Python.
We use the base64 encoding scheme to encode the string and strict, which throws a UnicodeDecodeError exception if the decoding fails.
str = "This is a shot on String encode() method in python";print "Encoded String: " + str.encode('base64','strict')
