String method encode() in Python

The string method encode() used to encode the string using specified encoding value. If encoding value not specified, the default value will be UTF-8, will be considered. It returns an encoded string.

Syntax

 1 <string>.encode(encoding=<encoding>, errors=<errors>)

string : A source string to encode using specified values

encoding : It specifies the encoding type to encode source string, if not specified, the default will be UTF-8, Optional. ie. utf-8, ascii etc

errors : An specifies the error method, if error occurs, Optional

Possible errors values

1. backslashreplace : it uses a backslash instead of the character that could not be encoded2. ignore : it ignores the characters that can not be encoded3. namereplace : It replaces the character with a text explaining the character4. strict : It causes an error on failure, it is default, if not specified5. replace : It replaces the character with a question mark6. xmlcharrefreplace : It replaces the character with an xml character

String method encode()

 1 msg = "Ståle Straße"
 2 
 3 # encoding string
 4 s1 = msg.encode()
 5 s2 = msg.encode(encoding="utf8",errors="backslashreplace")
 6 s3 = msg.encode(encoding="utf8",errors="ignore")
 7 s4 = msg.encode(encoding="ascii",errors="namereplace")
 8 s5 = msg.encode(encoding="ascii",errors="replace")
 9 s6 = msg.encode(encoding="ascii",errors="backslashreplace")
 10 
 11 # print encoded string
 12 print(s1)
 13 print(s2)
 14 print(s3)
 15 print(s4)
 16 print(s5)
 17 print(s6)

In the above example, a string variable is define with special character. A string is encoded with different encoding and errors values. An encoded string is assigned to variable that printed on console.

Output

 1 b'St\xc3\xa5le Stra\xc3\x9fe'
 2 b'St\xc3\xa5le Stra\xc3\x9fe'
 3 b'St\xc3\xa5le Stra\xc3\x9fe'
 4 b'St\\N{LATIN SMALL LETTER A WITH RING ABOVE}le Stra\\N{LATIN SMALL LETTER SHARP S}e'
 5 b'St?le Stra?e'
 6 b'St\\xe5le Stra\\xdfe'

Example 2

 1 str1 = "string in string !"
 2 
 3 s1 = str1.encode(encoding="utf8",errors="backslashreplace")
 4 print('Encoded string :', s1)

Output

 1 Encoded string : b'string in string !'
