In Python, element conversion has been a very useful utility as it offers it in a much simpler way that other languages. This makes Python a robust language and hence knowledge of interconversions is always a plus for a programmer. This article discusses the hexadecimal string to a decimal number. Let’s discuss certain ways in which this can be performed.
Method #1 : Using int()
This function can be used to perform this particular task, adding an argument (16) this function can convert hexadecimal string number to base sixteen and convert it into integer at the same time.
# Python3 code to demonstrate# converting hexadecimal string to decimal# Using int() # initializing string test_string = 'A' # printing original string print("The original string : " + str(test_string)) # using int()# converting hexadecimal string to decimalres = int(test_string, 16) # print resultprint("The decimal number of hexadecimal string : " + str(res)) |
The original string : A The decimal number of hexadecimal string : 10
Method #2 : Using ast.literal_eval()
We can perform this particular function by using literal evaluation function that predicts the base and converts the number string to its decimal number format.
# Python3 code to demonstrate# converting hexadecimal string to decimal# Using ast.literal_eval()from ast import literal_eval # initializing string test_string = '0xA' # printing original string print("The original string : " + str(test_string)) # using ast.literal_eval()# converting hexadecimal string to decimalres = literal_eval(test_string) # print resultprint("The decimal number of hexadecimal string : " + str(res)) |
The original string : A The decimal number of hexadecimal string : 10
