Python是一种高级编程语言,由Guido van Rossum在1991年开发。它以其简洁明了的语法和强大的标准库而著称,使得Python成为初学者和专业人士的优选编程语言。
name = "Python"
age = 30
height = 5.9 # 5英尺9英寸
is_student = Falseresult = 10 - 5
if result > 5: print("结果是大于5的")if result > 5: print("结果是大于5的")
elif result == 5: print("结果是等于5的")
else: print("结果是小于5的")def greet(name): print(f"Hello, {name}!")
greet("Python")import math
print(math.sqrt(16))with open("example.txt", "w") as file: file.write("Hello, World!")
with open("example.txt", "r") as file: content = file.read() print(content)class Dog: def __init__(self, name, age): self.name = name self.age = age def bark(self): print(f"{self.name} says: Woof!")

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(('localhost', 12345))
server_socket.listen(5)
client_socket, addr = server_socket.accept()
print(f"连接地址: {addr}")
client_socket.sendall(b"Hello, client!")
client_socket.close()
server_socket.close()import threading
def print_numbers(): for i in range(1, 11): print(i)
thread1 = threading.Thread(target=print_numbers)
thread2 = threading.Thread(target=print_numbers)
thread1.start()
thread2.start()
thread1.join()
thread2.join()通过以上教程,您已经掌握了Python编程的基础知识和进阶技巧。现在,您可以开始编写自己的Python程序,并在实践中不断提高自己的技能。祝您在编程世界中取得成功!
