Detailed explanation of Python operators: Let you easily master Python operators, you need specific code examples

Introduction:
Python is a simple and powerful programming language , which provides many operators that allow us to perform various calculations easily. This article will explain in detail the commonly used operators in Python and help readers better understand through specific code examples.

1. Arithmetic operators:
Arithmetic operators are used to perform basic mathematical operations, such as addition, subtraction, multiplication, division, etc.

1. Addition operator ( ):
   The addition operator is used to add two numbers, for example:

   num1 = 10
   num2 = 5
   sum = num1 + num2
   print("两数之和为：", sum)

   The output result is: the sum of the two numbers is: 15

2. Subtraction operator (-):
   The subtraction operator is used to subtract one value from another value, for example:

   num1 = 10
   num2 = 5
   difference = num1 - num2
   print("两数之差为：", difference)

   Output result is: The difference between the two numbers is: 5

3. ##Multiplication operator (*):

   The multiplication operator is used to multiply two values, for example:
   

   num1 = 10
   num2 = 5
   product = num1 * num2
   print("两数之积为：", product)

   The output result is: the product of two numbers is: 50

4. Division operator (/):

   The division operator is used to divide one value by another value, for example ：
   

   num1 = 10
   num2 = 5
   quotient = num1 / num2
   print("两数之商为：", quotient)

   The output result is: the quotient of two numbers is: 2.0

5. Modulum operator (%):

   The modulo operator is used to obtain two numbers. The remainder after dividing two numbers, for example:
   

   num1 = 10
   num2 = 5
   remainder = num1 % num2
   print("两数之余为：", remainder)

   The output result is: the remainder of the two numbers is: 0

6. Power operator (**):

   The power operator is used to calculate the exponential power of a value, for example:
   

   num = 2
   exponent = 3
   result = num ** exponent
   print("2的3次方为：", result)

   The output result is: 2 raised to the third power: 8

2. Comparison operators :

Comparison operators are used to compare the relationship between two numerical values ​​and return the corresponding Boolean value (True or False).

1. Equality operator (==):

   Equality operator is used to determine whether two values ​​are equal, for example:
   

   num1 = 10
   num2 = 5
   print(num1 == num2)

   The output result is: False

2. Inequality operator (!=):

   The inequality operator is used to determine whether two values ​​​​are not equal. For example:
   

   num1 = 10
   num2 = 5
   print(num1 != num2)

   The output result is: True

##Greater than operator (>):
3. Greater than operator is used to determine whether a value is greater than another value, for example:

   num1 = 10
   num2 = 5
   print(num1 > num2)

   
   The output result is : True
   ##Less than operator (<):
Less than operator is used to determine whether a value is less than another value, for example:

4. num1 = 10
   num2 = 5
   print(num1 < num2)

   Output result Is: False
   

   Greater than or equal to operator (>=):
The greater than or equal to operator is used to determine whether a value is greater than or equal to another value, for example:

5. num1 = 10
   num2 = 5
   print(num1 >= num2)

   The output result is: True
   

   ## Less than or equal to operator (<=):

   The less than or equal to operator is used to determine whether a value is less than or equal to another value. , for example:

num1 = 10
num2 = 5
print(num1 <= num2)

6. The output result is: False

   
   

   3. Assignment operator:

   The assignment operator is used to convert a numerical value (or the value of an expression ) is assigned to a variable.

Simple assignment operator (=):

The simple assignment operator is used to assign a value to a variable, for example:

num = 10
print(num)

1. The output result is: 10

   
   

   ##Addition assignment operator (=):

   The addition assignment operator is used to add a variable to a value and assign the result to the variable, for example:

   num = 10
   num += 5
   print(num)

The output result is: 15

2. 
   

   Subtraction assignment operator (-=):

   The subtraction assignment operator is used to subtract a value from a variable, and Assign the result to the variable, for example:

   num = 10
   num -= 5
   print(num)

The output result is: 5

3. 
   

   Multiplication assignment operator (*=):

   The multiplication assignment operator is used Used to multiply a variable by a value and assign the result to the variable, for example:

   num = 10
   num *= 5
   print(num)

The output result is: 50

4. 
   

   Division assignment operator (/ =):

   The division assignment operator is used to divide a variable by a value and assign the result to the variable, for example:

   num = 10
   num /= 5
   print(num)

The output result is: 2.0

5. 
   

   Modulo assignment operator (%=):

   The modulo assignment operator is used to take the remainder of a variable and assign the result to the variable, for example:

   num = 10
   num %= 4
   print(num)

Output The result is: 2

6. 
   ## 4. Logical operators:

   Logical operators are used to combine multiple conditions and return the corresponding Boolean value (True or False) according to the result of the condition. .

AND operator (and):

AND operator is used to determine whether two conditions are true at the same time. The result is true only when both conditions are true, for example :

num1 = 10
num2 = 5
bool1 = num1 > 0 and num2 < 10
bool2 = num1 > 100 and num2 < 10
print(bool1)
print(bool2)

The output result is:

True
1. False

   
   

   Or operator (or):
   The or operator is used to judge two Whether at least one condition is true, as long as one condition is true, the result will be true, for example:
   

   num1 = 10
   num2 = 5
   bool1 = num1 > 0 or num2 < 10
   bool2 = num1 > 100 or num2 < 10
   print(bool1)
   print(bool2)

   The output result is:
True
2. True

   
   

   Non-operator (not):
   The non-operator is used to negate the value of a condition. If the condition is true, the result is false; if the condition is false, the result is true, for example:
   

   bool1 = True
   bool2 = not bool1
   print(bool1)
   print(bool2)

   The output result is:
True
3. False

   
   

   5. Bit operators:
   Bit operators are used to perform various bit operations on binary numbers.
   

Bitwise AND operator (&):

The bitwise AND operator is used to perform an AND operation on each bit of two binary numbers. Only the two corresponding bits are both When it is 1, the result is 1, for example:

num1 = 10  # 二进制：0b1010
num2 = 5   # 二进制：0b0101
result = num1 & num2
print(result)

输出结果为：0

按位或运算符（|）：
按位或运算符用于对两个二进制数的每个位执行或操作，两个相应位只要有一个为1，结果就为1，例如：

num1 = 10  # 二进制：0b1010
num2 = 5   # 二进制：0b0101
result = num1 | num2
print(result)

输出结果为：15

按位异或运算符（^）：
按位异或运算符用于对两个二进制数的每个位执行异或操作，相应位相同为0，相应位不同为1，例如：

num1 = 10  # 二进制：0b1010
num2 = 5   # 二进制：0b0101
result = num1 ^ num2
print(result)

输出结果为：15

按位取反运算符（~）：
按位取反运算符用于对一个二进制数的每个位取反，即0变为1，1变为0，例如：

num = 10  # 二进制：0b1010
result = ~num
print(result)

输出结果为：-11

左移运算符（<<）：
左移运算符用于将一个二进制数的各个位左移指定的位数，空出的位以0填充，例如：

num = 10  # 二进制：0b1010
result = num << 2
print(result)

输出结果为：40

右移运算符（>>）：
右移运算符用于将一个二进制数的各个位右移指定的位数，空出的位以0填充，例如：

num = 10  # 二进制：0b1010
result = num >> 2
print(result)

输出结果为：2
