0 basic python-5.2 expression operators

An expression is the most basic tool for working with numbers

a=1# constant a=a+1# expression

Operator

Operator	Describe
Yield	Generator function Send protocol
Lambda args:expression	Generating anonymous functions
X if y else Z	Three-dimensional expression
X or Y	Logical OR (existence of short-circuit algorithm)
X and y	Logic and (existence of short-circuit algorithm)
Not X	Logical Non-
X in Y, x not in Y	Member relationships
X is y, X was not y	Object Entity Testing
X<y,x<=y,x>y,x>=y,x==y,x!=y	Compare size
X|y	Bit or, set merge set
X^y	Bit XOR, set symmetry difference
X&y	Bit and, set intersection
X<<y,x>>y	Move left or right y position
X+y,x-y	Add and subtract, merge delete
x*y,x%y,x/y,x//y	Multiply, take the remainder, except, the floor
-x,+x	One-dollar subtraction
~x	bitwise complement (negation)
X**y	Power operation
X[i]	Index, Function call
X[I:J:K]	Sharding
X (...)	Calling functions
X.attr	Call Properties
()	Tuples, expressions, generators
[]	List, list resolution
{}	Dictionary, Collection, collection, and dictionary parsing

3. Priority level

The table above is sorted by priority, the higher the precedence, the same as the priority of the same row

4. If there is a parenthesis in the expression, the parentheses take precedence

(1+2) *31+2*3

5. When the type is mixed, the type is automatically upgraded

Sort from numeric complexity: shaping, floating point, plural

So if the shaping is combined with a floating-point type, the result is a floating-point type

Right here, thank you.
