rounding fractions to 0 1 2 or 1

Recently encountered in the work of the score processing, find the relevant data discovery can be implemented using the fraction class, so the following article is mainly about the use of the standard library fractions module Let Python support the

Integer divided by integerAfter entering Python interaction mode (later in this tutorial, you may no longer repeat this kind of narration, just see >>>, as shown in interactive mode), practice the Following:2 / 50>>> 2.0 / 50.4>>> 2 / 5.00.4>>> 2.0 /

"Problem description"It's a classic game to count 24 points on 4 cards. General requirements are only allowed with subtraction and parentheses for arithmetic.For example: 1,2,3,4 can calculate 24 with the expression (1+2+3)-24.It is required to

Floating-point dataRepresentation of a non-integerIn addition to integers, the usual calculation is inseparable from the non-integers, that is, those numbers with fractional parts. In a digital system, integers and non-integers are called rational
