How to import the class within the same directory or sub directory?

Question

I have a directory that stores all the .py files.

bin/
   main.py
   user.py # where class User resides
   dir.py # where class Dir resides
         


        

Answer 1

If user.py and dir.py are not including classes then

from .user import User
from .dir import Dir

is not working. You should then import as

from . import user
from . import dir

Answer 2

I'm not sure why this work but using Pycharm build from file_in_same_dir import class_name

The IDE complained about it but it seems it still worked. I'm using Python 3.7

Answer 3

Python3

use

from .user import User inside dir.py file

and

use from class.dir import Dir inside main.py
or from class.usr import User inside main.py

like so

Answer 4

To make it more simple to understand:

Step 1: lets go to one directory, where all will be included

$ cd /var/tmp

Step 2: now lets make a class1.py file which has a class name Class1 with some code

$ cat > class1.py <<\EOF
class Class1:
    OKBLUE = '\033[94m'
    ENDC = '\033[0m'
    OK = OKBLUE + "[Class1 OK]: " + ENDC
EOF

Step 3: now lets make a class2.py file which has a class name Class2 with some code

$ cat > class2.py <<\EOF
class Class2:
    OKBLUE = '\033[94m'
    ENDC = '\033[0m'
    OK = OKBLUE + "[Class2 OK]: " + ENDC
EOF

Step 4: now lets make one main.py which will be execute once to use Class1 and Class2 from 2 different files

$ cat > main.py <<\EOF
"""this is how we are actually calling class1.py and  from that file loading Class1"""
from class1 import Class1 
"""this is how we are actually calling class2.py and  from that file loading Class2"""
from class2 import Class2

print Class1.OK
print Class2.OK
EOF

Step 5: Run the program

$ python main.py

The output would be

[Class1 OK]: 
[Class2 OK]:

Answer 5

Just too brief, Create a file __init__.py is classes directory and then import it to your script like following (Import all case)

from classes.myscript import *

Import selected classes only

from classes.myscript import User
from classes.myscript import Dir

Answer 6

from user import User 
from dir import Dir
