You've got a comma followed by a plus sign in there, so I'm not exactly
sure where the parameters to which function begin and end.
When it starts to look like this, I begin breaking out the parameters:
label = 'Days Since Jan 22'
size = geom_point(size=.1, color='blue')
theme = theme_bw()
g2 = ggplot(df2, aes(label, size, theme))
# Compose a long string:
msg = ('A very long line .....\n'
+ 'Another long bit of text ....'
+ 'plus another ....'
)
If all the pieces are constants, then Python will concatenate them for
you:
msg = ('A very long line .....\n'
'Another long bit of text ....'
'plus another')
Yes, the "+" sign is not actually needed in Python, but I find it's
helpful anyway. Using one also mirrors the use of other operators, such
as "or", where you cannot omit the operator. Another matter of taste ...
You can even mix in "f" strings:
msg = ('long line\n'
f'left text {name} right text'
'more here')
But watch out for missing spaces between the pieces! :-)
The PEP-8 rules are good, but they can't cover all cases perfectly.
Some the PEP-8 rules are debatable. Regardless, they can't cover all
cases perfectly. (IOW, we agree on the bit that's relevant to this
thread.)
