2,747 PointsSmall questions: why key.title() instead of just key? And why no ** example?
Hi!
In the last example, Kenneth Love used key.title()
in the .format()
call instead of just key
, even though (I believe) the latter would work just as well. I'm sure he had a reason for this; just wondering what it is.
Also, found it kind of strange that he prepped us to be able to use a ** when looping over a dictionary's items, but did not use it in any example. What was the reason for this / where can an example of such be found in this course?
Thanks! and Be Well, Graham

could have been used. The value of key
, at this point, is a string holding the dictionary key. Since this string is of type str
, the method .title()
is available. From help(str.title):
title(...) method of builtins.str instance
S.title() -> str
Return a titlecased version of S, i.e. words start with title case
characters, all remaining cased characters have lower case.

.title()
was a case! I assumed it was just the 'title' of thekey
