The previous post was for commands Unix. This post is about the Python commands I use or Google frequently.

1. To find the absolute path of the directory of the current file being executed -

   abs_path = os.path.dirname(os.path.realpath(file))

2. To copy a file from source to destination (using shutil)-

   from shutil import copyfile copyfile(src, dst)

3. To copy a file or directory from source to destination (using shutil)-

4. To create a directory if it doesn’t exist -

   import os if not os.path.exists(directory): os.makedirs(directory)

5. To write a JSON to a file -

   import json with open(‘data.json’, ‘w’) as f: json.dump(data, f)
