Python calculation example of md5 value of file

Smaller file processing method:

import hashlib
import os
 
def get_md5_01(file_path):
  md5 = None
  if os.path.isfile(file_path):
    f = open(file_path,'rb')
    md5_obj = hashlib.md5()
    md5_obj.update(f.read())
    hash_code = md5_obj.hexdigest()
    f.close()
    md5 = str(hash_code).lower()
  return md5
 
if __name__ == "__main__":
  file_path = r'D:\test\test.jar'
  md5_01 = get_md5_01(file_path)
  print(md5_01)

Larger file processing method:

import hashlib
import os
 
def get_md5_02(file_path):
  f = open(file_path,'rb') 
  md5_obj = hashlib.md5()
  while True:
    d = f.read(8096)
    if not d:
      break
    md5_obj.update(d)
  hash_code = md5_obj.hexdigest()
  f.close()
  md5 = str(hash_code).lower()
  return md5
 
if __name__ == "__main__":
  file_path = r'D:\test\test.jar'
  md5_02 = get_md5_02(file_path)
  print(md5_02)

Description: For the same file, two The md5 calculated by the method is consistent.

Note: The above code passed the test in Python 3.x version.

The above example of calculating the md5 value of a file in python is all the content shared by the editor. I hope it can give you a reference, and I hope you will support the PHP Chinese website.
