Thanks! But I see that there are two periods now:

c.execute("UPDATE {tn} SET {cn}='sebastian_r' WHERE {idf}=123456".\
          .format(tn=table_name, idf=id_column, cn=new_column))

Could you please remove the upper one?

Ah, sorry! I just realized that the places that I thought periods were needed, were just included above instead of on the new line! I'll let you close this unless you'd like for me to change them all for consistency.

No worries, and I think it's visually a bit misleading. I think we could leave it as is. It has a bit of those "when you see you old code and cringe" moments ;) I would put the period onto the new line if I wrote it today. Sth like

c.execute("UPDATE {tn} SET {cn}='sebastian_r' WHERE {idf}=123456"
          .format(tn=table_name, idf=id_column, cn=new_column))

(the backslash shouldn't be needed because of the parentheses.)

👍 sounds good to me. Sorry for the confusion!

No worries, I appreciate it that you submitted a PR helping to fix it :)
