Introduction
Functions
Functions are away to organize code. They are used to divide a problem into a smaller ones that are easier to manage.
Functions take inputs and process or carry out actions on them. They could also produce an out.
Types of Function:
1. User defined function
2. Imported or external function: like
from tkinter import *
3. Built in function: like print( ) , input( )
Example One:
def function2(x):
return 2*x
a=function2(3)
print(a)
Example Two:
def add(a,b):
added = a+b
return added
def minus(a,b):
diff= a-b
return diff
num1=float(input("Enter first number:"))
num2=float(input("Enter second number"))
total = add(num1,num2)
print(total)
subtract = minus(num1,num2)
print(subtract)
Task
Challenges:
1.Create a function that Accept two int values from the user and return their product. If the total is greater than 1000, then return their sum.
2.Design a program with functions to calculate the area of a rectangle.
3.Design a program with functions to calculate the perimeter of a rectangle.
4. Create a calculator using functions: Follow the video to create a calculator.
