min = num1 if num1<num2 else num2
print("Minimum Value:",min)

Output

Program for minimum of 3 numbers?

Python

num1 = int(input("Enter First Number:"))
num2 = int(input("Enter Second Number:"))
num3 = int(input("Enter Third Number:"))
min = num1 if num1<num2 and num1<num3 else num2 if num2<num3 else num3
print("Minimum Value:", min)

Output

PowerShell

Enter First Number:12
Enter Second Number:17
Enter Third Number:16
Minimum Value: 12

Program for maximum of 3 numbers?

Python

num1 = int(input("Enter First Number:"))
num2 = int(input("Enter Second Number:"))
num3 = int(input("Enter Third Number:"))
max = num1 if num1>num2 and num1>num3 else num2 if num2>num3 else num3
print("Maximum Value:", max)

Output
