Python String Encode Decode Exercise

Solution

Python encode()

Python has predefined encode() method to encode the string. It comes with a number of built in codecs, like - ascii, big5, latin_1, utf_7, utf_8 etc. If no any encoding codec specified, by default UTF-8 will be used.

Syntax of Python Encoding

string.encode(encoding, errors) 

Here, both encoding and errors are optional parameters. The encoding parameter by default take UTF-8.

Python decode()

Python has predefined decode() method to decode the string. This works opposite of encode. It accepts the encoding of the encoded string to decode it and returns the original string.

This is the following solution to encode and decode the given string -

str = "Hello Friend! Welcome to this tutorial."
 
# string encoding 
str_enc = str.encode('base64', 'strict')
 
print "The encoded string is : ",
print str_enc
 
# string decoded
print "The decoded string is : ",
print str_enc.decode('base64', 'strict')

Output of the above code
