Frequently Used Python Commands

This post is about the Python commands I use or Google frequently.

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

import os

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

• Using shutil

from shutil import copyfile, copy

copyfile(src, dst) # To copy a file from source to destination (using shutil)
copy(src, dst)     # To copy a file or directory from source to destination (using shutil)

• To create a directory if it doesn’t exist

import os

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

• To write a JSON to a file

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