Python में Multiple Imports कैसे करें?

Python में Multiple Imports

तरीका 1: Multiple Import Statements

>>> import os
>>> import math
>>> import sys

तरीका 2: Single Statement में Multiple Modules (Comma-separated)

>>> import math, sys, os

तरीका 3: Module Aliases के साथ

>&>> import math as Mathematics, sys as system

तरीका 4: String List से Dynamic Import (__import__)

>>> modnames = ["os", "sys", "math"]
>>> for lib in modnames:
...     globals()[lib] = __import__(lib)

तरीका 5: importlib का उपयोग (Modern, Python 3.1+)

import importlib

modnames = ["os", "sys", "math"]
modules = {name: importlib.import_module(name) for name in modnames}

# Access
modules['os'].getcwd()
modules['sys'].version

Best Practices (PEP 8):

• Imports को File के Top पर रखें
• Groups में Organize करें: Standard Library, Third-party, Local
• Groups के बीच Blank Line रखें
• Wildcard Imports (import *) से बचें
• Absolute Imports को Prefer करें Relative Imports पर

Example of Well-organized Imports:

# Standard Library
import os
import sys
from pathlib import Path
from typing import List, Optional

# Third-party
import requests
import numpy as np
import pandas as pd

# Local
from mypackage import utils
from . import config
