Check your mastery of Python operators: Comprehensive introduction to Python operators

Python Operator Encyclopedia: See which Python operators you have mastered, need specific code examples

Python is a simple and powerful programming language that provides A variety of operators are used to perform various numerical and logical operations. In this article, I will introduce you to Python's various operators in detail and provide code examples to help you understand better.

1. Arithmetic operators:
   Python provides common arithmetic operators, including addition (), subtraction (-), multiplication (), division (/), remainder ( %), exponentiation (*) and round division (//). Here is some sample code:

a = 10
b = 3

print(a + b)  # 输出：13
print(a - b)  # 输出：7
print(a * b)  # 输出：30
print(a / b)  # 输出：3.3333333333333335
print(a % b)  # 输出：1
print(a ** b) # 输出：1000
print(a // b) # 输出：3

2. Comparison operators:
   Comparison operators in Python are used to compare the size of two values ​​and return a Boolean value (True or False) . Comparison operators include equal (==), not equal (!=), greater than (>), less than (<), greater than or equal to (>=), and less than or equal to (<=). Here is some sample code:

a = 3
b = 5

print(a == b)  # 输出：False
print(a != b)  # 输出：True
print(a > b)   # 输出：False
print(a < b)   # 输出：True
print(a >= b)  # 输出：False
print(a <= b)  # 输出：True

3. Assignment operator:
   The assignment operator in Python is used to assign a value or expression to a variable. Common assignment operators include equal (=), plus equal (=), minus equal (-=), multiplication equal (*=), division equal (/=), etc. Here is some sample code:

a = 10
b = 5

c = a + b   # c = 15
a += b     # a = 15
a -= b     # a = 10
a *= b     # a = 50
a /= b     # a = 10.0

4. Logical operators:
   Logical operators in Python are used to handle Boolean operations in conditional statements. Including and (and), or (or) and not (not). Here is some sample code:

a = True
b = False

print(a and b)  # 输出：False
print(a or b)   # 输出：True
print(not a)    # 输出：False

5. Bit operators:
   Python provides bit operators for performing bit operations on binary numbers. Bitwise operators include bitwise AND (&), bitwise OR (|), bitwise XOR (^), bitwise negation (~), left shift (<<) and right shift (> >). Here is some sample code:

a = 10  # 十进制：1010
b = 5   # 十进制：0101

print(a & b)   # 输出：0
print(a | b)   # 输出：15
print(a ^ b)   # 输出：15
print(~a)      # 输出：-11
print(a << 1)  # 输出：20
print(a >> 1)  # 输出：5

This is just a subset of the operators provided by Python. In actual programming, problems can be better solved by flexibly using various operators as needed. I hope that through these code examples, you can better understand and master the use of Python operators.
