python - unicode regex match - how do I search for the checkmark? ✓

Question

I am trying to match against lines that contain a checkmark in them: ✓

I'm using python3.

The unicode encoding can be read about here: https://codepoints.net/U+2713?lang=en

The line I'm trying to match against looks like this:

✓ Chrome on MAC - MySite.com - version-1

re.match("✓", line) does not work. re.match("/u2713", line) does not work either.

How can I determine if the line contains a ✓?

--- UPDATE ---

solved: apparently there was an invisible character of some sort preceding the ✓ and this caused the match operator to fail. Thanks to @NickT and @EricDuminil for clueing me in. Also, the in operator appears to be easier and safer, so I'm marking that answer as correct.

Answer 1

You don't even need any regex. You could use the in operator:

>>> "✓" in "✓ Chrome on MAC - MySite.com - version-1"
True
>>> "✓" in "Chrome on MAC - MySite.com - version-1"
False

If you want to display the lines with a checkmark inside 'marks.txt', you can write:

with open('marks.txt') as f:
    for line in f:
        if "✓" in line:
            print(line, end='')

Answer 2

For a fool-proof method, specify the character by name:

>>> line = '✓ Chrome on MAC - MySite.com - version-1'
>>> re.match('\N{CHECK MARK}', line)
<_sre.SRE_Match object; span=(0, 1), match='✓'>
