Module to handle automatic variable naming, multiple files and some file acrobatics in python

Project Description


This module is designed to create variables for files that are to be accessed collectively. Since files tend to take up a lot of memory, it is not advised to use this module to keep multiple files in a directory open. The mapper works by creating variables with same file name and maps them(Do not confuse this for the built-in maps() function) to their file location. These variables can then be accessed like regular files using read(). All the functions defined here return a tuple of successfully processed files.


Tested Combinations:
  • Windows 10/8/7
  • Most Linux Distros
  • Python (3.5,3.4,2.7)

Using this module in any combination other than those listed above may produce unexpected results.

Unfortunately this module is currently incompatable with OSX, so do not install it without proper undertsanding of the source code.


pip install filemapper


>>>import filemapper as fm
>>>help(fm) #This will display help for this module
Creating variables
>>>import filemapper as fm
>>>print fm.create('resources') #Creates variables for files within the folder resources
>>>f = open('nouns.dat')) #Passed into read() before it can be used.
>>>for i in f:print i #Prints out the whole 'nouns.dat'
[Trunctuated 90959 Lines]

Example Case

>>>f = fm.create('resources')
>>>new_f = [sub_f[0] for sub_f in f.items()]
>>>for i in new_f: #Only prints the content of files that start with 'a'
...    if i[0] == 'a':
...        for x in  open(i, 'r'):print x
[Stdout Ommitted due to large size]
Loading Files
>>>print fm.load('resources','w') #Omittiing the second argument will default to read only mode
>>>for i in'nouns.dat'):print i
[Stdout Ommitted due to large size]
Closing Files
>>>fm.close() #Closes all the files
