How to open every file in a folder

Question

I have a python script parse py  which in the script open a file  say file1  and then do something maybe print out the total number of characters    filename    file1  f   open filename   r   content   f read   print filename  len content    Right now  I am using stdout to direct the result to my output file - output  python parse py  gt  gt  output   However  I don t want to do this file by file manually  is there a way to take care of every single file automatically  Like  ls   awk   print     python parse py  gt  gt  output    Then the problem is how could I read the file name from standardin   or there are already some built-in functions to do the ls and those kind of work easily   Thanks

you should try using os walk  yourpath    path   import os for root  dirs  files in os walk yourpath  topdown False       for name in files          print os path join root  name           stuff     for name in dirs          print os path join root  name           stuff

You can actually just use os module to do both    list all files in a folder sort files by file type  file name etc     Here s a simple example   import os  os module imported here location   os getcwd     get present working directory location here counter   0  keep a count of all files found csvfiles       list to store all csv files found at location filebeginwithhello        list to keep all files that begin with  hello  otherfiles       list to keep any other file that do not match the criteria  for file in os listdir location       try          if file endswith   csv                print  csv file found  t   file             csvfiles append str file               counter   counter 1          elif file startswith  hello   and file endswith   csv     because some files may start with hello and also be a csv file             print  csv file found  t   file             csvfiles append str file               counter   counter 1          elif file startswith  hello                print  hello files found   t   file             filebeginwithhello append file              counter   counter 1          else              otherfiles append file              counter   counter 1     except Exception as e          raise e         print  No files found here    print  Total files found  t   counter     Now you have not only listed all the files in a folder but also have them  optionally  sorted by starting name  file type and others  Just now iterate over each list and do your stuff

The code below reads for any text files available in the directory which contains the script we are running  Then it opens every text file and stores the words of the text line into a list  After store the words we print each word line by line   import os  fnmatch  listOfFiles   os listdir      pattern      txt  store      for entry in listOfFiles      if fnmatch fnmatch entry  pattern            fileName   open entry  r           if  fileName mode     r               content    fileName read               contentList   content split                  for i in contentList                  if i      n  and i      r n                       store append i   for i in store      print i

Os You can list all files in the current directory using os listdir  import os for filename in os listdir os getcwd        with open os path join os getcwd    filename    r   as f    open in readonly mode         do your stuff  Glob Or you can list only some files  depending on the file pattern using the glob module  import glob for filename in glob glob    txt       with open os path join os cwd    filename    r   as f    open in readonly mode         do your stuff  It doesn t have to be the current directory you can list them in any path you want  path     some path to file  for filename in glob glob os path join path     txt        with open os path join os getcwd    filename    r   as f    open in readonly mode         do your stuff  Pipe Or you can even use the pipe as you specified using fileinput import fileinput for line in fileinput input          do your stuff  And then use it with piping  ls -1   python parse py
