You must use float.fromhex and float.hex

float.fromhex('0x1.5c28f5c28f5c3p-1')
Output: 0.68

You can use a library which is known as ast
To install this library you need to type:- pip install AST
eg:-

from ast import literal_eval 
data = "0xAB15"
out = literal_eval(data) 
print(out)

you will get the output:- 43797
