Python String encode() Method

By Lenin Mishra

If you prefer to watch Youtube videos over reading blogs, check out our video on Python strings here.

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

Syntax of encode() method

string.encode(encoding, errors)

encoding: Encoding to use(optional)
          Default value is UTF-8.
errors:	Required Error method(Optional)

Check out the list of standard encodings with Python.

You can use the following error values.

  1. backslashreplace - use a backslash instead of the character that could not be encoded
  2. ignore - ignore the characters that cannot be encoded.
  3. namereplace - replace the character with a text explaining the character.
  4. strict - Default, will raise an error on failure.
  5. replace - replace the character with a question mark.
  6. xmlcharrefreplace - replace the character with an xml character.

Python is only going to use these above error types, if it runs into some error while encoding.

Example 1 - Simple encoding to UTF-8

Code

str1 = "I like Pylenin"

print(str1.encode())

Output

b'I like Pylenin'
Example 2 - Encoding a Non-ASCII string to ASCII

Code

str1 = "Pylenin like �pples"

print(str1.encode('ASCII', errors='backslashreplace'))
print(str1.encode('ASCII', errors='ignore'))
print(str1.encode('ASCII', errors='namereplace'))
print(str1.encode('ASCII', errors='replace'))
print(str1.encode('ASCII', errors='xmlcharrefreplace'))

Output

b'Pylenin like \\xe4pples'
b'Pylenin like pples'
b'Pylenin like \\N{LATIN SMALL LETTER A WITH DIAERESIS}pples'
b'Pylenin like ?pples'
b'Pylenin like äpples'
