Example of a user-defined function
Functions without arguments
Example: 1
Write a python script using a function to calculate and print square of a number
#function definition
def square():
a=int(input("Enter any no "))
b=a*a
print("square = ",b)
#function calling
square()
Output:
Enter any no 5
square = 25
>>>
Example: 2
Write a python script using a function to calculate and print cube of a number
#function definition
def cube():
a=int(input("Enter any no "))
b=aaa
print("cube = ",b)
#function calling
cube()
Output:
Enter any no 5
cube = 125
>>>
Example:3
Write a python script using a function to calculate and print sum of two numbers?
#function definition
def sum():
a=int(input("Enter 1st no "))
b=int(input("Enter 2nd no "))
c=a+b
print("Sum = ",c)
#function calling
sum()
Output:
Enter 1st no 10
Enter 2nd no 20
Sum = 30
>>>
Example:4
Write a python script using function to take input for three numbers check and print the largest number?
#function definition
def largest():
a=int(input("Enter 1st no "))
b=int(input("Enter 2nd no "))
c=int(input("Enter 3rd no "))
if(a>b and a>c):
m=a
elif(b>c):
m=b
else:
m=c
print("Largest number = ",m)
#function calling
largest()
Output:
Enter 1st no 25
Enter 2nd no 96
Enter 3rd no 35
Largest number = 96
>>>
Example:5
Write a python script using function to take input for two numbers calculate and print their sum, product and difference?
#function definition
def cal():
a=int(input("Enter 1st no "))
b=int(input("Enter 2nd no "))
s=a+b
p=a*b
if(a>b):
d=a-b
else:
d=b-a
print("Sum = ",s," Product = ",p," diff = ",d)
#function calling
cal()
Output:
Enter 1st no 10
Enter 2nd no 20
Sum = 30 Product = 200 diff = 10
