Why do we write this method after the variable, unlike
Some methods, like
len( ), are built into Python and can be used on lots of different things. Others, like
lower( ), belong to strings, and can only be used attached to strings, and that’s why you see them attached at the end of a string instead of being on their own with a string inside their parentheses. A lesson on this exact topic, with more detail, is coming up soon!
