3#take input from the user
4value1=input(int("Enter the Value 1"))
5value2=input(int("Enter the Value 2"))
6value3=input(int("Enter the Value 3"))
7
8#now compare the values
9if (value1>value2) and (value1>value3):
10  largest=value1
11elif (value2>value1) and (value2>value3):
12  largest=value2
13else:
14  largest=value3
15
16#print the largest value
17print("The largest value is",largest)

3# change the values of num1, num2 and num3
4# for a different result
5num1 = 10
6num2 = 14
7num3 = 12
