Python string Method - encode()

The encode() method in Python strings returns an encoded version of the string using a specified encoding. The encoding is specified as an argument to the encode() method.

The syntax for the encode() method is as follows:

string.encode(encoding, errors)

Here, string is the string that we want to encode, encoding is the encoding that we want to use (optional, default is 'utf-8'), and errors is the error handling scheme to use for encoding errors (optional, default is 'strict').

Example:

# Defining a string
my_string = "hello world"

# Using the encode() method
encoded_string = my_string.encode('base64')

print(encoded_string)   # Output: "aGVsbG8gd29ybGQ=\n"

In the above example, the encode() method is used to encode the string my_string using the 'base64' encoding. The resulting encoded string is stored in encoded_string, which is printed using the print() function. Note that the encode() method returns a bytes object, not a string object. To convert the bytes object back to a string object, we can use the decode() method. For example:

# Using the decode() method
decoded_string = encoded_string.decode('base64')

print(decoded_string)   # Output: "hello world"

In the above example, the decode() method is used to decode the bytes object encoded_string using the 'base64' encoding. The resulting decoded string is stored in decoded_string, which is printed using the print() function. Note that the decode() method returns a string object, not a bytes object.
