Fun fact: In math, complex numbers are traditionally denoted with the letter z as it’s the next letter in the alphabet after x and y, which commonly represent coordinates.The complex number factory function accepts two numeric parameters. The first one represents the real part, while the ...

Lexicographical ordering essentially means "similar to alphabetical ordering". For example, "animal" < "apple" is True because since the first letters are equivalent, the second letters are compared and "n" < "p" (in both Unicode and the alphabet). Likewise, (1969, 5, 18) < (1969, 7,...
