python将参数传递给函数

def greet(name):
    print("Hello, " + name + "!")

greet("John")

# 定义一个带有默认参数的函数
def greet(name, greeting="Hello"):
    print(greeting + ", " + name + "!")

greet("John")  # 输出 "Hello, John!"
greet("John", "Hi")  # 输出 "Hi, John!"

# 定义一个带有可变参数的函数
def print_numbers(*args):
    for num in args:
        print(num)

print_numbers(1, 2, 3, 4)  # 输出 1, 2, 3, 4

# 定义一个带有关键字参数的函数
def print_info(name, **kwargs):
    print("Name:", name)
    for key, value in kwargs.items():
        print(key + ":", value)

print_info("John", age=30, city="New York")  # 输出 "Name: John", "age: 30", "city: New York"
