Python - String Method - encode() Tutorial

 It will return an encoded version of the string, using the specified encoding. If no encoding is specified, UTF-8 will be used by default.

Syntax-

String.encode(encoding="encoding", errors="errors")

#encoding- (Optional) It will specify the encoding to be used.
By default, it will use UTF-8 encoding
#errors- (Optional) It is to specify the error method
some of the error methods are-
ignore	- It will ignore the characters that cannot be encoded
namereplace	- It will replace the character with a text explaining the character
backslashreplace - It will replace the character with a backslash that could not be encoded
strict	- It will raise an error on failure
replace	- It will replace the character with a question mark
xmlcharrefreplace	- It will replace the character with an XML character

Example-  

str1 = "Hello Pythön ß"
print(str1.encode())
print(str1.encode(encoding="UTF-8",errors="backslashreplace"))
print(str1.encode(encoding="ascii",errors="backslashreplace"))
print(str1.encode(encoding="ascii",errors="ignore"))
print(str1.encode(encoding="ascii",errors="namereplace"))
print(str1.encode(encoding="ascii",errors="replace"))
print(str1.encode(encoding="ascii",errors="xmlcharrefreplace"))

b'Hello Pyth\xc3\xb6n \xc3\x9f'
