I want to convert hex to decimal value for the bellow given .txt file . specifically in line number 1, only for 73cb for that purposes I have developed python program . BUT it does not work and my output should be: 29643
(10 (0 1 73cb 0))
(13 (0 1 e7ba 0))
(12 (0 1 0 0))
(10 (2 1 73cb 1 3)(
-0.05492209987825172 0.2133354572857093 0.2934898883481872
-0.05491927490082463 0.211290383138306 0.2817208459424883
-0.04367581308239386 0.212758053576771 0.287530716703097
))
with open("test.txt","r") as fi:
id = []
for ln in fi:
if ln.startswith("(10"):
id.append(ln[9:13])
sd=print(id)
dec=int(sd,16)
print(dec)
You have assigned the value of variable sd to print() which will return None.
What you need to do is to convert the ln[9:13] to int and then convert it from hexadecimal to decimal.
A code modified from yours is
with open("test.txt","r") as fi:
id = []
for ln_count, ln in enumerate(fi):
if ln.startswith("(10") and ln_count == 0:
sd=ln[9:13]
id.append(sd)
dec=int(sd,16)
print(dec)
Additionally, I would recommend changing the variable name id to something else since id is the name of an inbuilt function in python. Using id as a variable name will cause function overriding.
