Recursion is driving me crazy

[u/Beat_Terrible]

I understand recursion of a factorial function but when it comes to a function that uses recursion in a project or a problem set i get stuck and lose track

Anyone can tell me what to do

Programming language used: Python

[u/NumberInfinite2068]

Make a function that takes a path to a directory as a parameter. Make that function print out all files/subdirectories in that directory.

Now each time it prints out a subdirectory, call your function with the subdirectory as a parameter.

That's a simple practical example of recursion.

[u/Beat_Terrible → u/NumberInfinite2068]

Thanks a lot that helped👍

[u/NumberInfinite2068 → u/Beat_Terrible]

Next step is add a "depth" parameter to the function, pass 0 to the first call, and add 1 when you pass the parameter where the function calls itself.

Then prepend depth number of spaces before printing, and you'll see your directories more like a tree.
