Python String encode() Method Example


Python string encode() is an inbuilt method that is used to convert unicodes of that string to any encodings that are supported by python. With the help of strings encode() method, we can Encoding is also essential as it holds the key in case of security. So to store different data in databases, it has become a need to use an encoding. For example, passwords are strings and to encode that in python, we use the encode() function.  Okay, but what is encoding? Let’s find output.

What is Encoding

First, we need to understand what is encoding. So to start within python, the strings are stored in the form of Unicode, and for increasing the efficiency of storage of the strings, these unicodes are converted in a set of bytes. This complete process is known as encoding. There are different encoding schemes defined in the language such as utf-8, ascii, ibm039, etc.

Python String encode()

The encode() method encodes the string, using a specified encoding. If no encoding is specified, then UTF-8 will be used.


string_var.encode(encoding, errors)

See the following parameters.

Encoding: Type of encoding in which the string is supposed to be encoded.

Errors: Response given when the encoding fails, there are about six encoding error responses.

It returns the encoded string.

In case of failure, it raises the UnicodeDecodeError exception.

Example programs on string encode() method

Write a program to show the mechanism of string encode()


str1 = "Hello and welcome to the world of pythön!"
str2 = str1.encode()


➜  pyt python3
b'Hello and welcome to the world of pyth\xc3\xb6n!'
➜  pyt

Write a program to encode a string bypassing both the parameters and show the output.


str1 = "Hello pythön!!"
print(str1.encode("ascii", "replace"))
➜  pyt python3
b'Hello pyth?n!!'
➜  pyt

In today’s world, security holds the key to many of the applications.

Thus the need for secure storage of passwords in the database is required, and hence there is to save encoded versions of strings.

We can 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.


Python encode() method encodes the string according to the provided encoding standard. By default, Python strings are in Unicode form but can be encoded to other standards also.

Finally, Python String encode() Method Example is over.
