Python Note 3 (Functions)

We can define number of functions in same python script.
Code

#function1
def cube(x) :
 return x**3

#function2
def maxVal(x,y) :
 if x > y :
  return x
 else :
  return y

print (cube(3))
print (maxVal(12,22))

Lets see how to import functions in another python script.
There are 2 importing methods

1. import a single function
2. import all functions under a "namespace"(python script)

• import a single function

assume we have implemented a function called factorial() in a python script named as mylib.py .

from mylib import factorial
print (factorial(4))

So we can call function directly.

Other way

import mylib
print (mylib.factorial(4))

In this method there may be some anomalies if we are going to import 2 functions with same name and signature in different scripts.
