The encode method in Python is utilized to encode a string based on the specified encoding format. While Python strings are inherently in Unicode format, they can also be converted to different encoding standards. The process of encoding involves transforming text from one coding system to another.
Python String encode Method Syntax
It has the following syntax:
encode(encoding="utf-8", errors="strict")
Parameters
- encoding : encoding standard, default is UTF-8
- errors : errors mode to ignore or replace the error messages.
Both are optional. Default encoding is UTF-8.
The error parameter is assigned a default value of 'strict' and also supports several alternative values, including 'ignore', 'replace', 'xmlcharrefreplace', 'backslashreplace', among others.
Return Type
It returns an encoded string.
Different Examples for Python String Encode Method
Let’s explore a few examples to gain a clearer understanding of the encode function.
Python String Encode Method Example 1
A straightforward approach to convert a Unicode string into the UTF-8 encoding format.
# Python encode() function example
# Variable declaration
str = "HELLO"
encode = str.encode()
# Displaying result
print("Old value", str)
print("Encoded value", encode)
Output:
Old value HELLO
Encoded value b 'HELLO'
Python String Encode Method Example 2
We are encoding a latin character
� into default encoding.
# Python encode() function example
# Variable declaration
str = "H�LLO"
encode = str.encode()
# Displaying result
print("Old value", str)
print("Encoded value", encode)
Output:
Old value H�LLO
Encoded value b'H\xc3\x8bLLO'
Python String Encode Method Example 3
When we attempt to encode a Latin character into ASCII, an error occurs. Refer to the example provided below.
# Python encode() function example
# Variable declaration
str = "H�LLO"
encode = str.encode("ascii")
# Displaying result
print("Old value", str)
print("Encoded value", encode)
Output:
UnicodeEncodeError: 'ascii' codec can't encode character '\xcb' in position 1: ordinal not in range(128)
Python String Encode Method Example 4
To disregard errors, provide 'ignore' as the second argument.
# Python encode() function example
# Variable declaration
str = "H�LLO"
encode = str.encode("ascii","ignore")
# Displaying result
print("Old value", str)
print("Encoded value", encode)
Output:
Old value H�LLO
Encoded value b'HLLO'
Python String Encode Method Example 5
It disregards the error and substitutes the character with a question mark.
# Python encode() function example
# Variable declaration
str = "H�LLO"
encode = str.encode("ascii","replace")
# Displaying result
print("Old value", str)
print("Encoded value", encode)
Output:
Old value H�LLO
Encoded value b'H?LLO'
