Answer 1

Yes, when using a function in the Python standard library, we need to import the library into our program before using the function.

For example

Code

#math library which contains various math functions like, pi,cos,sin etc.
import math
#using pi function to find area of circle of radius 7 units
r=7
print('Area is : ', math.pi*r*r)

Output
