title: How to make a file transfer program in python
body: <p>The title might not be relevant for my question becuase I don't actually want a wireless file transfering script, I need a file manager type.</p>
  
  <p>I want something with which I can connect my phone with my pc (eg: hotspot and wifi) and then I would like to show text file browser (I have the code for that) by sending lists of all files and folders using <code>os.listdir()</code>, whenever the selected option is a file (<code>os.path.isdir() == False</code>), I would like to transfer the file and run it(like: picture, video, etc).</p>
  
  <p>The file Browser code which I wrote runs on windows and also Android (after making a few changes) using <code>qpython</code>.</p>
  
  <p>My code is</p>
  
  <pre><code>import os
  def FileBrowser(cwd = os.getcwd()):
    while True:
      if cwd[-1:] != "\\":
        cwd = cwd + "\\"
      files = os.listdir(cwd)
      count = 1
      tmpp = ""
      print("\n\n" + "_"*50 +"\n\n")
      print(cwd + "\n")
      for f in files:
        if os.path.isdir(cwd + f) == True:
          s1 = str(count) + ". " + f
          tmps1 = 40 - (len(s1)+5)
          t2 = int(tmps1/3)
          s1 = s1 + " " * t2 + "-" * (tmps1 - t2)
          print(s1 + "&lt;dir&gt;")
        else:
          print(str(count) + ". " + f + tmpp)
        count = count + 1
      s = raw_input("Enter the file/Directory: ")
      if s == "...":
        tmp1 = cwd.count("\\")
        tmp2 = cwd.rfind("\\")
        if tmp1 &gt; 1:
          cwd = cwd[0:tmp2]
          tmp2 = cwd.rfind("\\")
          cwd = cwd[0:tmp2+1]
          continue
        else:
          continue
      else:
        s = int(s) - 1
      if os.path.isdir(cwd + files[s]) == True:
        cwd = cwd + files[s] + "\\"
        continue
      else:
        f1 = files[s]
        break
    return f1
  def main():
    fb = FileBrowser()
  main()
