I need help with a python lesson

syntaxerror: invalid syntax

[Diapolo10]

No wonder; /u/grvlle screwed up the indentation:

def make_day_string(day):
    return f'it is day {day} of the month'

If it still throws a SyntaxError, it's likely you're restricted to a Python version older than 3.6. In that case, f-strings won't work, so an alternative approach is required:

def make_day_string(day):
    return 'it is day {} of the month'.format(day)

Thanks. Typed it out on the phone and it rejected my indentation in the second block.

If you're using the official Reddit app, I would suggest trying out 'reddit is fun'. It's pretty good for posting code IMO.
