Finding the level of recursion call in python
<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>
