What are wildcard imports in Python?
Wildcard imports in Python allow you to import all names from a module using the syntax from module import *
. This can be convenient but may lead to namespace pollution.
What are the risks of using wildcard imports?
The main risks include potential name clashes, making it unclear where a name came from, and reducing code readability.
When should I avoid using wildcard imports?
You should avoid wildcard imports in larger projects or modules where clarity and maintainability are important.
Can you give an example of a wildcard import?
Sure! For example, from math import *
allows you to use functions like sin()
and cos()
directly without prefixing them with math.
