The string method decode() used to decode the string using specified decoded value. If decoding value not specified, the default value will be UTF-8, will be considered. It returns the original string from the encoded string.
1 <string>.decode(encoding = <encoding>, errors = <errors>)
string : A encoded source string to decode using specified values.
encoding : It specifies the encoding on the basis of which decoding has to be performed. ie. utf-8, ascii etc
errors : An specifies the error method, if error occurs, Optional
| 1. | backslashreplace : it uses a backslash instead of the character that could not be encoded. |
| 2. | ignore : it ignores the characters that can not be encoded. |
| 3. | namereplace : It replaces the character with a text explaining the character. |
| 4. | strict : It causes an error on failure, it is default, if not specified. |
| 5. | replace : It replaces the character with a question mark. |
| 6. | xmlcharrefreplace : It replaces the character with an xml character. |

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 decoded by using decode() function and print the original string on console.
