Program Listing

# To find the largest of three numbers

print()
print("\tLargest of Three Numbers in Python");
print()

# take inputs
num1 = int(input('\tEnter first number: '))
num2 = int(input('\tEnter second number: '))
num3 = int(input('\tEnter third number: '))

# find largest numbers
if (num1 >= num2) and (num1 >= num3):
    largest = num1
elif (num2 >= num1) and (num2 >= num3):
    largest = num2
else:
    largest = num3

# display result
print();
print('\tThe largest number = ', largest)
print();
print("\tEND OF PROGRAM");
print();
