List installed packages:
pip list
# or

pip install package-name
# or
pip3 install package-nameFor example, to import PIL, install pillow:
pip install pillowCreate and activate a virtual environment to isolate dependencies:
python3 -m venv myenv
source myenv/bin/activate # On Linux/Mac
myenv\\Scripts\\activate # On Windows
pip install package-nameVerify your import statement is correct:
# Correct
import numpy
from pandas import DataFrame
# Incorrect
import numpy as np # This works but imports 'numpy' package
import nump # Typo - package name is 'numpy'Some packages have different import names than package names (e.g., install 'Pillow' but import 'PIL', install 'pyyaml' but import 'yaml'). Check PyPI documentation for the correct import name.
