Python program to convert hex string to decimal

Method # 1: Using int()

This function can be used to accomplish this specific task by adding an argument (16) which can convert the hexadecimal number of the string to hexadecimal base and simultaneously convert it to an integer.

# Python3 demo code
# convert hex string to decimal
# Using int ()

  
# initialization string

test_string = ` A`

 
# print original line

print ( "The original string:" + str (test_string))

 
# using int ()
# convert hex string to decimal

res = int (test_string, 16 )

  
# print result

print ( "The decimal number of hexadecimal string:" + str (res ))

Output:

 The original string: A The decimal number of hexadecimal string: 10 

Method # 2: Using ast.literal_eval()

We can accomplish this particular function using the literal evaluation function that predicts the radix and converts a numeric string to its decimal number.

# Python3 demo code
# convert hex string to decimal
# Using ast.literal_eval ()

from ast import literal_eval

  
# initialization string

test_string = ` 0xA`

 
# print original line

print ( "The original string:" + str (test_string))

 
# using ast.literal_eval ()
# transform hex string to decimal

res = literal_eval (test_string)

 
# print result

print ( "The decimal number of hexadecimal string:" + str < code class = "plain"> (res))

Output:

 The original string: A The decimal number of hexadecimal string: 10
