Answer 1

"split()" method splits a given string whenever it finds a match for the given string.
In this case, you've split(" ") means it'll split the string whenever it'll find a space and it'll return a list ['Emily', 'Kathie'].

"string[start :end]" this method is used to slice the string from index 'start' to index 'end-1'.
[:1] ==[0:1] and will take out the 0 index of the string i.e. 'E' from Emily and 'K' from Kathie.

"join()" method takes a list of 'str' types as argument and join them by keeping in between whatever you want. ex. ','.join(list) will join the elements of the list with a comma in between.
In your case, it's ''.join(list) so it'll join elements with keeping in between nothing.
So, it'll create a string from 'E' and 'K' with nothing in between as 'EK'.
