I have a variable call hex_string. The value could be '01234567'. Now I would like to get a hex value from this variable which is 0x01234567 instead of string type. The value of this variable may change. So I need a generic conversion method.

Use hex() to convert a string to hex Use int(x, base) with 16 as base to convert the string x to an integer. Call hex(number) with the integer as number to convert it to hexadecimal.
hex() function in Python. hex() function is one of the built-in functions in Python3, which is used to convert an integer number into it's corresponding hexadecimal form. Syntax : hex(x) Parameters : x - an integer number (int object) Returns : Returns hexadecimal string.
When denoting hexadecimal numbers in Python, prefix the numbers with '0x'. Also, use the hex() function to convert values to hexadecimal format for display purposes.
To convert a hexadecimal string to a numberUse the ToInt32(String, Int32) method to convert the number expressed in base-16 to an integer. The first argument of the ToInt32(String, Int32) method is the string to convert. The second argument describes what base the number is expressed in; hexadecimal is base 16.
I think you might be mixing up numbers and their representations. 0x01234567 and 19088743 are the exact same thing. "0x01234567" and "19088743" are not (note the quotes).
To go from a string of hexadecimal characters, to an integer, use int(value, 16).
To go from an integer, to a string that represents that number in hex, use hex(value).
>>> a = 0x01234567
>>> b = 19088743
>>> a == b
True
>>> hex(b)
'0x1234567'
>>> int('01234567', 16)
19088743
