 Generator expressions are short-form [generators][generators] - lazy iterators that produce their values _on demand_, instead of saving them to memory.
 This generator expression is consumed by [`str.join()`][str-join], which joins the generated letters together using an empty string.

 Since the generator expression and `join()` are fairly succinct, they are put directly on the `return` line rather than assigning and returning an intermediate variable for the acronym.

 A [`list comprehension`][list comprehension] is then used to iterate through the phrase and select the first letters of each word via [`bracket notation`][subscript notation].
 This comprehension is passed into [`str.join()`][str-join], which unpacks the `list` of first letters and joins them together using an empty string - the acronym.
