No output is shown. But why ?

Question

#A python code to finding out
#maximum number among the three

def max(num1,num2,num3):
#finding out of maximum number
if (num1 >num2 )and (num1 >num3 ):
print ("num1 is the largest number",num1 )
elif (num2 >num1 )and (num2 >num3 ):
print ("num2 is the largest number",num2 )
else :
print ("num3 is the largest number",num3 )
#driver code
max(10,20,30)
print("The largest number is:max")

Answer 1

1. Your "driver code" is inside the else block inside the function. Just fix the indentation.
2. The last print call outputs the string "max". Is this your intention?
