encode( ) FUNCTION

encode( ) Function

The encode( ) Function is used to encode the String. By default UTF-8 is used.

Example :

x = "Héllo"
y = x.encode()
print("The encoded string is ",y)

Output :

The encoded string is b'H\xc3\xa9llo'

In the above code, we have declared a String 'Héllo' with a special character 'é' and assigned it to a variable 'x'.

x = "Héllo"

And we have used the 'encode( )' function to encode the String with UTF-8(i.e. The default).

y = x.encode( )

And we get the below output.

The encoded string is b'H\xc3\xa9llo'

Now, if you want to specify a custom encoding other than UTF-8. Python gives us the flexibility to do that as well in a second parameter. Also there is a third parameter that is used for errors.

A popular encoding is 'ascii'. Let us understand the below example with all the errors available.

Example :

x = "Héllo"
print(x.encode(encoding="ascii",errors="backslashreplace"))
print(x.encode(encoding="ascii",errors="ignore"))
print(x.encode(encoding="ascii",errors="namereplace"))
print(x.encode(encoding="ascii",errors="replace"))
print(x.encode(encoding="ascii",errors="xmlcharrefreplace"))

Output :

b'H\\xe9llo'
b'Hllo'
b'H\\N{LATIN SMALL LETTER E WITH ACUTE}llo'
b'H?llo'
'Héllo'
