The logical operatorsANDandORare also provided to allow you to join two or more expressions. TheNOToperator can also be given before an expression. =and<>can also be considered logical operators. However, unlikeANDorORthey can't be used to join more than two expressions. Example: > 10 a =...
While these three lines (three statements) do constitute a proper Python program, they are more likely a small piece of a larger program. The lines of text in this program fragment look similar to expressions in algebra. We see no sequence of binary digits. Three words,subtotal, tax, ...
