Python Base value operator

First, arithmetic operators

The arithmetic operators have the following types:

+: Addition

-: Subtraction

*: Multiplication

/: Division, which is the real division, the result shows the number of decimal parts

%: Take-over, two-digit division of the remainder

* *: power operation, e.g. 3**2 result of 9

: In addition to the floor, the results show only the whole number of parts

Second, comparison operators

Comparison operators have the following concentrations:

= =: equals

! =: Not equal, recommended use

<>: Not equal to, Python3 has been abandoned

: Greater Than

<: Less than

>=: greater than or equal to

<=: Less than or equal to

Three, assignment operators

The assignment operators have the following types of values:

=: The simplest assignment, such as a=2

+=:a+=2, equivalent to a=a+2

-=:a-=2, equivalent to A=a-2

*=:a*=2, equivalent to A=a*2

/=:a/=2, equivalent to A=A/2

%=:a%=2, equivalent to a=a%2

**=:a**=2, equivalent to A=a**2

=:a//=2, equivalent to A=A//2

Four, logical operators

There are several logical operators:

And: Logic and, only the two sides of the conditions are set up, and finally set up. For example true and true result is true,true and false result is false

Or: Logical OR, both sides of the condition as long as one side is established, and finally set up. For example true or false result is true

Not: logical non, conditional negate. For example not true result is false,not false result is true

Priority: Not>and>or
