Unpacking Dictionaries Unexpected

my_string = "Hi, my name is {} and I live in {}."
my_string.format("Sergio", "Colomobia")
'Hi, my name is Sergio and I live in Colomobia.'

in the video kenneth got an KeyError when he put their name and location between single quotes but instead I've put double quotes and apparently it works.. why?

The difference is that in the first line of my_string....you didn't put anything between the {}...in the video he does and that is why his method got a KeyError

By looking at some responses in stack overflow, simple quotes and double quotes are interchangeable (in python), they are a matter of taste. http://stackoverflow.com/questions/56011/single-quotes-vs-double-quotes-in-python

Hello Sergio,

As far as I know, there's no difference between single and double quotes in this case. I tried the example with single quotes without exception. Maybe there's something else he did in combination that caused the error.

I hope this helps.
