I'm trying to read bytes from a DAT file. I know the data is supposed to be in either Binary or Hex. But when I try to read the bytes it prints out weird symbols. I'm assuming they are ascii values. I tried converting them but I keep getting the error message that 'str' cannot be converted. Does anyone know how I can decode it? And is read() the correct function to use for this?
import time
import binascii
import csv
import serial
with open('Example CARESCAPE Datalog.dat') as binary_file:
for num in range(1,10):
data = binary_file.readline()
print(data)
If your .dat
file is not text, you should open it as a binary file with 'b'
(per Python docs ):
with open('Example CARESCAPE Datalog.dat', 'b') as binary_file:
You'll have to decode the bytes yourself:
Files opened in binary mode (including 'b' in the mode argument) return contents as bytes objects without any decoding.
