How can I pass a block of code to a function for it to perform within itself?
For example, I wrote a small function that recurses through a
directory structure but keeps a track of the depth:
from path import path
def traverse(directory, depth=0):
thedir = path(directory)
for item in thedir.files():
## Do stuff relative to the depth
for item in thedir.dirs():
traverse(item,depth+1)
What I want to do is something like:
from path import path
def traverse(directory, depth=0, things_to_do()):
thedir = path(directory)
for item in thedir.files():
things_to_do(depth)
for item in thedir.dirs():
traverse(item,depth+1)
Is this possible?
Thanks
Ed
