Functions without arguments and not returning any values
In this, we do not pass any arguments to the function and the function does not return any value.
Examples:
Question:1
Write a python script using functions to calculate and print square of a number
Sol:
#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
>>>
Question:2
Write a python script using function to calculate and print cube of a number
Sol:
#function definition def cube(): a=int(input("Enter any no ")) b=a*a*a print("Cube = ",b) #function calling cube()
Output:
Enter any no 5
Cube = 125
>>>
Question:3
Write a python script using function to take input for two numbers calculate and print their sum, product and difference.
Sol:
Method:1 Using Single Function
#function definition def calculate(): 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) print("Prod = ",p) print("Diff = ",d) #function calling calculate()
Output:
Enter 1st no 10
Enter 2nd no 20
Sum = 30
Prod = 200
Diff = 10
>>>
Method:2 (Using Multiple functions)
#function definition def sum1(): a=int(input("Enter 1st no ")) b=int(input("Enter 2nd no ")) s=a+b print("Sum = ",s) def prod(): a=int(input("Enter 1st no ")) b=int(input("Enter 2nd no ")) p=a*b print("prod = ",p) def diff(): a=int(input("Enter 1st no ")) b=int(input("Enter 2nd no ")) if(a>b): d=a-b else: d=b-a print("diff = ",d) def avg(): a=int(input("Enter 1st no ")) b=int(input("Enter 2nd no ")) av=(a+b)/2 print("avg = ",av) #function calling sum1() prod() diff() avg()

Output:
Enter 1st no 10
Enter 2nd no 20
Sum = 30
Enter 1st no 2
Enter 2nd no 3
prod = 6
Enter 1st no 25
Enter 2nd no 6
diff = 19
Enter 1st no 2
Enter 2nd no 6
avg = 4.0
>>>
Question:4
Write a python using function to take input for 3 numbers check and print the maximum number.
Sol:
#function definition def largest(): a=int(input("Enter 1st no ")) b=int(input("Enter 2nd no ")) c=int(input("Enter 2nd no ")) if(a>b and a>c): m=a elif(b>c): m=b else: m=c print("Max no = ",m) #function calling largest()
Output:
Enter 1st no 25
Enter 2nd no 96
Enter 2nd no 3
Max no = 96
>>>
Question:5
Write a python script using function to take input for 3 numbers check and print the lowest number.
Sol:
#function definition def lowest(): a=int(input("Enter 1st no ")) b=int(input("Enter 2nd no ")) c=int(input("Enter 2nd no ")) if(a<b and a<c): m=a elif(b<c): m=b else: m=c print("Min no = ",m) #function calling lowest()
Output:
Enter 1st no 25
Enter 2nd no 963
Enter 2nd no 4
Min no = 4
>>>
