[Python] Facing an issue with executing python package

I am learning python packages but I am stuck with this issue: I created one package folder "SamplePack". Inside this folder, I have added 2 module files with .py extension and an __ init __.py file as a constructor as below:

Mod2.py

from math import *

def sqroot(x):
return sqrt(x)

def sine(x):
return sin(x)

def cos(x):
return cos(x)

def power(x,y):
return pow(x,y)


Mod1.py

def Add(x,y):
return x+y

def Div(x,y):
return x-y

def function():
x=input("What's your name? ")
y=input("Great", x, "What's your phone number? ")


__ init __.py

import Mod1
import Mod2


Post this, I created the package source file from which I will execute these package modules.

Packuse.py

import SamplePack as sp

sp.Mod1.Add(20,20)
sp.Mod2.sqrt(30)
sp.Mod1.function()


When I executed the Packuse.py file through python prompt. I got this error:

C:\Users\Program>python packuse.py Traceback (most recent call last): File "C:\Users\Program\packuse.py", line 1, in import SamplePack as sp File "C:\Users\Program\SamplePack_init_.py", line 1, in import Mod1 ModuleNotFoundError: No module named 'Mod1'
