Import opened a entire part of the Module but what means (from import . It opened the half part of modules?? What i dont understand it. Can u explain??

Answer 1

I'm not sure what you're talking about. Here is the lesson on modules in the Python 3 course:

https://www.sololearn.com/learn/Python/2438/

If you're not on mobile or you don't have access to the lessons yet, here is a basic explanation (assuming you're talking about using the from keyword for importing). I'll try to explain this using an example. There is a function called sqrt() in the math module that allows you to get the square root of a number. One way of importing and using it is this:

import math
math.sqrt(number)

If you don't want to have to use the "math." part, you can do this instead:

from math import sqrt
sqrt(number)

If you replace import sqrt with import *, I think you pretty much import everything in that module, so this works too:

from math import *
sqrt(number)

Hope that clears it up.
