Python packages and compresses and reads files of specified types in specified directories

The following is a code to introduce to you the specified type files in the python package and compress the specified directory. The specific code is as follows:

import os
import datetime
import tarfile
import fnmatch
def find_spe_file(root, patterns=['*'], non_cludedir=[]):
  for root, dirnames, filenames in (root):
    for pattern in patterns:
      for filename in filenames:
        if (filename, pattern):
          #print(filename)
          yield (root, filename)
def cre_tarfile():
  args = ["*.jpg", "*.jepg"]
  now = ().strftime("%Y_%m_%d_%H_%M_%S")
  filename = "all_img_{0}.".format(now)
  with (filename, mode='w:gz') as f:
    for item in find_spe_file(".", args):
      #print(item)
      (item)
if __name__ == "__main__":
  cre_tarfile()

Let's take a look at using python to read the specified type file in the specified directory

Preparation: Set the specified path and use the () method to obtain all files under the path

import os
path = "d:\\data"              # Set pathdirs = (path)          # Get the file under the specified path

Loop judgment: Use the () method to filter out files of the specified type

for i in dirs:               # Loop to read the file under the path and filter the output  if (i)[1] == ".csv":  # Filter csv files    print i              # Output allcsvdocument

Case display:

# encoding: utf-8
import os
path = "d:\\data"              # Set pathdirs = (path)          # Get the file under the specified pathfor i in dirs:               # Loop to read the file under the path and filter the output  if (i)[1] == ".csv":  # Filter csv files    print i              # Output allcsvdocument

Running results:

Function explanation:

(path)

Function function: Returns a list containing the name of the entry in the directory specified by the path. The list is in any order. It does not include special entries '.' and '..', even if they exist in the directory.

import os, sys
path = "d:\\tmp\\"
dirs = ( path )
for file in dirs:
  print (file)

Running results:

Java Multiple
Java Multiple Inheritance_files

ParallelPortViewer

(path)

Function function: Separate file name and extension; return (fname, fextension) tuple by default, and can be sliced

import os, sys
path = 'c:\\csv\\'
print (path)

Running results:

('c:\\csv\\test', '.csv')
