How to implement three mesh operations in Python

The three-mesh operator in C language

The code is as follows:

Expression expr1:expr2; Expression is true to take the value of EXPR1, otherwise take EXPR2 value

Python three Mesh implementation method:

(1) expr= judgment expression and expr1 or expr2

The expression is true, and if Expr1 is True then Expr=expr1, false or EXPR2,EXPR=EXPR2.

When the expression is false, it becomes false or expr2, and EXPR=EXPR2.

As long as the expression Expr1,expr2 is true, the above equation is the same as in C.

expr= judgment expression? EXPR1:EXPR2;

(2) min (x, y) = (×
(3) min (x,y=x if x
