What are some ways to use import function in Python?

Question

How can I use import function in Python?

Answer 1

in Python the import statement is used to bring in modules (built-in or external) so you can use their functions classes and variables. Here are the main ways you can use it:
1) Import a whole module
import math
print(math.sqrt(16))

2) Import with an alias (shorter name)
import numpy as np
arr = np.array([1, 2, 3])

3) Import specific functions or classes
from math import sqrt, pi
print(sqrt(25))
print(pi)

4) Import everything (not recommended)
from math import *
print(sin(0))

5) Dynamic import inside code
module_name = "random"
random_module = __import__(module_name)
print(random_module.randint(1, 10))

Best practice: Use specific imports or aliases so your code stays clean and readable. Good Luck!

Silvio Micheloto ,

for a more detailed information and insight about importing, you can check the description of the python `importlib` modul. (it is probably not for everyday use).
