I\'ve tried to find a comprehensive guide on whether it is best to use import module
or from module import
. I\'ve just started with Python and I\'m
The difference between import module
and from module import foo
is mainly subjective. Pick the one you like best and be consistent in your use of it. Here are some points to help you decide.
import module
import
statements. Don't need to add any additional imports to start using another item from the modulemodule.foo
in your code can be tedious and redundant (tedium can be minimized by using import module as mo
then typing mo.foo
)from module import foo
foo
import
statementfoo
. For example, it's less clear what ceil()
does compared to math.ceil()
Either method is acceptable, but don't use from module import *
.
For any reasonable large set of code, if you import *
you will likely be cementing it into the module, unable to be removed. This is because it is difficult to determine what items used in the code are coming from 'module', making it easy to get to the point where you think you don't use the import
any more but it's extremely difficult to be sure.
