reading lines from a string [Solved]

[ebolisa]

No. text is a string. It does not contain lines. It contains newline characters.

In the old code you wrote it to a file, read it back, and counted the number of times 'Bluetooth:' appears in the file. If the count was greater than zero, you called a function.

Can you count the number of times 'Bluetooth:' appears in a string?

If you mean some like this, it doesn't work:

count = 0

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

nlines = text.count('\n')

for i in range(nlines):
    if text.find('Bluetooth:'):
        count += 1
print(count)
