title: Finding the level of recursion call in python
body: <p>I have a function which is called recursively and I want to know the current level of recursion. Below code shows the method that I am using to calculate it, but it is not giving the expected results.</p>
  
  <p>E.g. : To find the recursion level for a system path:</p>
  
  <pre><code>    import os
      funccount = 0
  
      def reccount(src):
          global funccount
          print "Function level of %s is %d" %(src, funccount)
  
      def runrec(src):
          global funccount
          funccount = funccount + 1
          lists = os.listdir(src)
          if((len(lists) == 0)):
              funccount = funccount - 1
          reccount(src)
          for x in lists:
               srcname = os.path.join(src, x)
               if((len(lists) - 1) == lists.index(x)):
                    if (not(os.path.isdir(srcname))):
                         funccount = funccount - 1
               if os.path.isdir(srcname):
                  runrec(srcname)
  
      runrec(C:\test)
  </code></pre>
  
  <p>Problem : Given a directory path, print the level of recursion for directory</p>
  
  <p>Directory Structure is :
  In my directory structure, i will call the function "reccount(Test)" (Function will be called with path to MainFolder). I want to know the level of recursion call for each folder. (Directory only)</p>
  
  <pre><code>Test:
     |----------doc
     |----------share
                  |----------doc
                              |----------file1
     |----------bin
                  |----------common
                               |----------doc
     |----------extras
     |----------file2
  </code></pre>
  
  <p>When i call the procedure, i get the following result:</p>
  
  <pre><code>    Function level of C:\test is 1
      Function level of C:\test\bin is 2
      Function level of C:\test\bin\common is 3
      Function level of C:\test\bin\common\doc is 3
      Function level of C:\test\doc is 3
      Function level of C:\test\extras is 3
      Function level of C:\test\share is 4
      Function level of C:\test\share\doc is 5
  </code></pre>
  
  <p>As you can see, when it prints results for bin/common/doc, it prints 3 instead of 4 and all subsequent results are wrong </p>
