Say you have created a Python file calculator.py and you want to access this file from another Python file then follow the below steps.
Step 1: Put the file inside a folder
Create a folder say calculator and add the calculator.py file in it.
def add(a, b):
return a + b
def subtract(a, b):
return a - b
Step 2: Create __init__.py
Next, create an empty __init__.py file within the same folder.
Step 3: Create another py file.
Now let's see various ways to access the calculator.py file from main.py
Example 1: Import the entire moduleimport calculator.calculator
result = calculator.calculator.add(5, 3)
print(result)
result = calculator.calculator.subtract(8, 4)
print(result)
Example 2: Import the entire module as alias
import calculator.calculator as calc
result = calc.add(5, 3)
print(result)
result = calc.subtract(8, 4)
print(result)
Example 3: Import specific functions from the module
from calculator.calculator import add, subtract
result = add(5, 3)
print(result)
result = subtract(8, 4)
print(result)
Example 4: Import all functions from the module
from calculator.calculator import *
result = add(5, 3)
print(result)
result = subtract(8, 4)
print(result)
