Python Basic 5-operator

First, arithmetic operators

Arithmetic operators	Assignment operators	Specific description	Example	Add
+	+=	Additive operations		X+=1 equivalent to X=x+1
-	-=	Subtraction operation		All assignment operators ibid.
*	*=	Multiplication operations
/	/=	Division operation
%	%=	Modulo arithmetic
**	**=	Power operation	2**3=8
//	//=	The integer operation	9//2=4

Two-bit operators

Bitwise operators	Specific description
&	Bitwise AND operation, 1&1=1, the remaining 0
|	bitwise OR operation, 1 is 1, otherwise 0
^	Bitwise XOR, same as 0, different 1
~	bitwise NON, ~0=1,~1=0
<<	Left-shift operation, all bits shifted to the left
>>	Right shift operation, all bits shifted right

Third, comparison operators

Comparison operators	Specific description
==
！ =	Inequality operator
<>	Unequal operators, same! =
<
>
<=
>=

Four, logical operators

logical operators	Specific description
and	Logic and operations
Or	Logical OR operation
Not	Logical non-operation

Five, string operators

Operator	Specific description
+	String connection
*	Repeating output string
[]	Get the position character by index, index starting from 0
[Start,end]	Intercept part of a string, from start to End-1
Inch	A member operator that returns true if the string contains the given character
Not in	Member operator, which returns true if the string does not contain the given character
R or R	Specifies the original string, which means that all strings are used directly as literal meanings, without escape characters, Special characters or characters that cannot be printed. The first quotation mark of the original string is preceded by the letter R or R

the precedence of the operator (top-to-bottom represents the high and low of the operation priority)

Meta operator	Specific description
**
~, +,-	Here the +,-refers to the plus or minus
*、/、%、//
+,-	Here the +,-refers to the addition and subtraction
>>, <<
&
^, |
>, = =,! =
%=,//= 、......	All assignment operators
is, is not	Identity operator
In, not in	Member operators
Not, or, and	logical operators
