Lecture: Creating a module

File name greet:

def hello():
    print('Welcome to the club')

File name demo

import greet

greet.hello()

Creating another function called bye.

def hello():
    print('Welcome to the club')

def bye():
    print('Goodbye, thanks for visiting')

Another way to import function from a module.

from greet import hello,bye

hello()
bye()

import random

result = random.randint(1,10)
print(result)

from random import randint

result = randint(1,10)
print(result)

import datetime

today_date = datetime.date.today()
current_time = datetime.datetime.now()
print(today_date)
print(current_time)
# but a better way to write above code is
from datetime import date
from datetime import datetime

today_date = date.today()
current_time = datetime.now()
print(today_date)
print(current_time)
