I believe every programmer has his/her own repository of coding snippets. I used to manage it with OneNote and EverNote. I am going to manage the core part here.

## python

• Iterate through all files in the current folder.
import os

for root, dirs, files in os.walk(os.getcwd()):
for name in files:
print(os.path.join(root, name))


## MATLAB

• Iterate through all files in the current folder and remove the root folders.
dirInput = dir(fpath);
dirInput(ismember({dirInput.name},{'.','..'})) = []; % remove hidden folder

• Make directory if not exist (one liner).
dirname = "name";
if ~exist(dirname, 'dir'), mkdir(dirname); end
