Working with multiple directory is one of the trickiest work in python. We will solve this trickiest work in simple way.

Defining base path using os.getcwd()

we will define currect working directory as basepath.

Our working path is ‘home/sagor/Desktop/hello’

import os

BASE_PATH = os.getcwd()
print(BASE_PATH)
# output: home/sagor/Desktop/hello

Done! initializing base path

Now we have three folder inside hello.

• src (contains source script)
• data (contains data files)
• logs (contains our logs file)

Adding these path to our base path using os.path.join

Now we add these path to our base path.

SRC_PATH = os.path.join(BASE_PATH, 'src')
DATA_PATH = os.path.join(BASE_PATH, 'data')
LOGS_PATH = os.path.join(BASE_PATH, 'logs')


# if we have a folder 'extra' outside 'hello', we can add too.

EXTRA_PATH = os.path.join(BASE_PATH, '../hello')

Now you can work these defined path inside your basepath.

Exampe work

We will print all the files inside DATA_PATH using os.listdir

files = os.listdir(DATA_PATH)

for file in files:
    print(file)
    
# output: 'hello.png''hello1.png'
