Conversion of Event Log Error Script to Python 3

I am having difficulty converting the following Python 2 script to Python 3. This script finds all Event Log errors and emails the results. I have changed the print theBody to print(theBody) but then the following error occurs. Any ideas how to fix this script are appreciated.

"Script Error embedded script error:
Script Error 'ascii' codec can't decode byte 0xc2 in position 7915: ordinal not in range(128)
Script Error Exception Traceback (most recent call shown last):

embedded script, line 15, at top level
File '/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/encodings/ascii.py', line 26, in decode
return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 7915: ordinal not in range(128)"

Code: Select all

import os
from datetime import date

baseDir = indigo.server.getInstallFolderPath()
tmpFileName = os.path.join(baseDir, 'Logs/tmp.txt')

fileDate = str(date.today())
eventFileName = os.path.join(baseDir, 'Logs/' + fileDate + ' Events.txt')

theBody = ''

with open(tmpFileName, 'a') as tmpFile:
    with open( eventFileName, 'r' ) as log:
        for line in log:
            if 'Error' in line:
               tmpFile.write(line)
               theBody += line

# theBody is the body of  an email which is sent next
print theBody

indigo.variable.updateValue(1155409051, value=theBody)

theSubject = "All Indigo Event Log Errors"

indigo.variable.updateValue(1695073597, value=theSubject)


Try this. In Python 3, strings are unicode, not bytes. But file IO is bytes. So you need to encode your string when you write it to a file.

Code: Select all

import os
from datetime import date

baseDir = indigo.server.getInstallFolderPath()
tmpFileName = os.path.join(baseDir, 'Logs/tmp.txt')

fileDate = str(date.today())
eventFileName = os.path.join(baseDir, 'Logs/' + fileDate + ' Events.txt')

theBody = ''

with open(tmpFileName, 'a') as tmpFile:
    with open( eventFileName, 'r' ) as log:
        for line in log:
            if 'Error' in line:
               tmpFile.write(line.encode('UTF-8'))
               theBody += line

# theBody is the body of  an email which is sent next
print theBody

indigo.variable.updateValue(1155409051, value=theBody)

theSubject = "All Indigo Event Log Errors"

indigo.variable.updateValue(1695073597, value=theSubject)


It might also be the line before, where you're looking for a string in the line read from the file. You could try changing that line to:

Code: Select all

            if b'Error' in line:


Which forces that string to a bytestring, which is same type as the file input buffer (line).

I haven't done much File IO in Python3, so I'm not sure the best way to do this.

See https://docs.python.org/3/tutorial/inpu ... ting-files

Adding the file encoding to the file open will handle most of the conversion by itself.

Thanks for the suggestion. It solved my problem just by including the encoding in the open file statement, namely:

with open(tmpFileName, 'a', encoding="utf-8") as tmpFile:
with open( eventFileName, 'r', encoding="utf-8") as log:

I run this script every evening to receive an email showing all Indigo errors that occurred during the day.
