Python determines instances of file and string encoding types

python determines file and string encoding types using the chardet toolkit, which recognizes most encoding types. However, when reading an Windows notepad saved txt file a few days ago, GBK was identified as KOI8-ES7en with no solution.

Then I wrote a simple code recognition method, the code is as follows:

coding.py

#  Description: UTF Compatible with ISO8859-1 and ASCII . GB18030 Compatible with GBK . GBK Compatible with GB2312 . GB2312 Compatible with ASCII
CODES = ['UTF-8', 'UTF-16', 'GB18030', 'BIG5']
# UTF-8 BOM The prefix byte 
UTF_8_BOM = b'\xef\xbb\xbf'

#  Gets the file encoding type 
def file_encoding(file_path):
 """
  Gets the file encoding type \n
 :param file_path:  The file path \n
 :return: \n
 """
 with open(file_path, 'rb') as f:
  return string_encoding(f.read())

#  Gets the character encoding type 
def string_encoding(b: bytes):
 """
  Gets the character encoding type \n
 :param b:  Bytes of data \n
 :return: \n
 """
 #  Traversal the encoding type 
 for code in CODES:
  try:
   b.decode(encoding=code)
   if 'UTF-8' == code and b.startswith(UTF_8_BOM):
    return 'UTF-8-SIG'
   return code
  except Exception:
   continue
 return ' Unknown character encoding type '

Note: file_encoding method is used to determine the file encoding type. The parameter is the file path. The string_encoding method is used to determine the string encoding type as the byte data corresponding to the string

Use examples:

import coding
file_name = input(' Please enter the path of the file to be identified: \n')
encoding = coding.file_encoding(file_name)
print(encoding)
