reading lines from a string [Solved]

[ebolisa]

Hi,

The code below works, but it has too many lines. I tried to shorten it, but I get OSError: [Errno 36] File name too long.

What am I doing wrong?
TIA

#!/usr/bin/python3
from subprocess import check_output
import os

filename = 'tmp.txt'

# get text and save to file
def readFile():
    global filename

    text = check_output('dmesg -T', shell = True).decode('utf-8')

    #write to a file
    file = open(filename,'w')
    file.write(text)
    file.close()


def analyzeFile():
    readFile()
    count = 0

    # read text from file
    with open(filename, 'r') as openfile:
        for line in openfile:
            for part in line.split():
                if 'Bluetooth:' in part:
                    count += 1
    if count > 0:
        emailme(count)


def emailme(txt):
#     print(txt)
    os.remove(filename)
    pass


analyzeFile()

short version:

count = 0
text = check_output('dmesg -T', shell = True).decode('utf-8')
with open(text, 'r') as openfile:
        for line in openfile:
            for part in line.split():
                if 'Bluetooth:' in part:
                    count += 1
print(count)
