Question

[Using Python]

I need my code given below to loop the user input, so that you are asked to input without it stopping after 4 inputs.

Code:

#A program that converts a hexadecimal number to its decimal value

#Define function for hexadecimal to decimal
def hexToDec(hexi):
result = 0

#For loop to test input for correct values
for char in hexi:
if 'A' <= char <= 'F' or 'a' <= char <= 'f':
if 'a' <= char <= 'f':
result = result * 16 + ord(char) - ord('a') + 10
else:
result = result * 16 + ord(char) - ord('A') + 10

elif 'G' <= char <= 'Z' or 'g' <= char <= 'z':
return "Incorrect hex number"

else:
result = result * 16 + ord(char) - ord('0')

#Display output
return "The decimal value for hex number {} is {}".format(hexi,result)

#Get input from user
print(hexToDec(input("Enter a hex number: ")))
print(hexToDec(input("Enter a hex number: ")))
print(hexToDec(input("Enter a hex number: ")))
print(hexToDec(input("Enter a hex number: ")))

Answer 1

#Input statement is inside loop. It will continuously ask user for input.

def hexToDec(hexi):
result = 0

#For loop to test input for correct values
for char in hexi:
if 'A' <= char <= 'F' or 'a' <= char <= 'f':
result = result * 16 + ord(char) - ord('a') + 10
elif 'G' <= char <= 'Z' or 'g' <= char <= 'z':
return "Incorrect hex number"
else:
result = result * 16 + ord(char) - ord('A') + 10

  

else:
result = result * 16 + ord(char) - ord('0')

#Display output
return "The decimal value for hex number {} is {}".format(hexi,result)

while(True):
print(hexToDec(input("Enter a hex number: ")))
