Question

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.

E.g. : To find the recursion level for a system path:

    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)

Problem : Given a directory path, print the level of recursion for directory

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)

Test:
   |----------doc
   |----------share
                |----------doc
                            |----------file1
   |----------bin
                |----------common
                             |----------doc
   |----------extras
   |----------file2

When i call the procedure, i get the following result:

    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

As you can see, when it prints results for bin/common/doc, it prints 3 instead of 4 and all subsequent results are wrong

Answer 1

def some_method(data, level=0):


    some_method(..., level=level+1)


if __name__ == '__main__':
    some_method(my_data)
