![]() In both the cases, the encoding used is the 'euc_kr' and the error used is 'strict'. The encoded string is now taken and the decode() function is invoked to that string and the decoded string is obtained as output and printed using the print() function. In the following example, a string "Hello! Welcome to Tutorialspoint." is created and it is encoded using the encode() function. If the error is specified as 'strict', then the encoding errors raise a UnicodeError. The python string decode() method that takes 'euc_kr' as its encoding has a variable length encoding done on korean characters. The decoded string is: Hello! Welcome to Tutorialspoint. ![]() On executing the above program, the following output is generated. Print("The decoded string is: ", str_decoded) Print("The encoded string is: ", str_encoded) Str_encoded= str.encode('utf_16','strict') In both the cases, the encoding used is the 'utf_16' and the error used is 'strict'. The decoded string is obtained as output and printed using the print() function. The encoded string is now taken and the decode() function is invoked to that string. The python string decode() method that takes 'utf_16' as its encoding has a variable length encoding done. The python string decode() method returns a decoded string. Other possible values are 'ignore', 'replace', 'xmlcharrefreplace', 'backslashreplace' and any other name registered via codecs.register_error(). The default for errors is 'strict' which means that the encoding errors raise a UnicodeError. For a list of all encoding schemes, please visit: Standard Encodings.Įrrors − This parameter specifies an error handling scheme. The following are the parameters of the python string decode() function.Įncoding − This parameter specifies the encodings to be used. Str.decode(encoding='UTF-8',errors='strict') The syntax of the python string decode() method is as follows. ![]() In the following section, we will be learning more details about the python string decode() method. Finally, this method returns the decoded string. During this process, different error handling schemes can be set using the errors parameter. ![]() Based on the specified encoding, the string is decoded. There are various types of standard encodings such as base64, ascii, gbk, hz, iso2022_kr, utf_32, utf_16, and many more. This function works based on the parameters specified which are encoding and the error. The encoded string can be decoded and the original string can be obtained with the help of this function. The python decode by default uses UTF-8.The python string decode() method decodes the string using the codec registered for its encoding.The python decode converts bytes to string objects.The python decode method is used to decode the encoded form of a string.Since the input id and the original password did not match thus we will display "Welcome". Now we will encode the stored password associated with this login id and compare. In the second case, the user is entering the login id as 'coder123' and the password as 'examplePassword'. Since the input id and the original password did not match thus we will display "sorry! You've entered the wrong password." In the first case, the user is entering the login id as 'coder123' and the password as 'myPassword'. In order to make the system more secure, we are storing the password in an encoded form using the encodedPassword variable. In the above example, we have a login_id and login_password. The actual message encryption is a far more complex process that is outside the scope of the article. Note: The given example represents the most basic case of message encoding-decoding in order to explain the implementation of encode and decode methods in python. These messages are then decoded and obtained in the original form. Message encryption is done when we want to send private messages that can't be snooped easily, thus we encode those messages and send that encoded form. The encode-decode in python can be used for message encryption. In this example, we will create a small message verification system using the python encode and python decode functions. Then this encoded string is passed to python decode which returns the decoded string. In the above example, we have taken the string python decode example, and then it is passed to example.encode(encoding='utf8') which returns an encoded string that is stored in encodedString.
