Need explanation for the below python code

I came across the below line in a piece of code written in python. Couldn't understand it. Please elaborate.

pancake_row = [p == '+' for p in line.split()[0]]

Well, it's a list comprehension which is a bit like a condensed for loop which only ever returns a list.

line is a str (but we only know this from the code because 'split' is a str method)

line.split()generates a list from the str (splitting at whitespace)

line.split()[0] is the first element of that list;

p == '+' returns a boolean, True or False, and will only ever run once;

So the only possible output is [True] or [False]
