使用一个或多个参数时如何传递函数参数

def add(a, b):
    return a + b

result = add(2, 3)
print(result)  # 输出 5

def add(a, b):
    return a + b

result = add(b=3, a=2)
print(result)  # 输出 5

def add(a, b=0):
    return a + b

result1 = add(2)
result2 = add(2, 3)
print(result1)  # 输出 2
print(result2)  # 输出 5

def add(*args):
    result = 0
    for num in args:
        result += num
    return result

result = add(2, 3, 4)
print(result)  # 输出 9

def print_info(**kwargs):
    for key, value in kwargs.items():
        print(f"{key}: {value}")

print_info(name="Alice", age=25, city="New York")
# 输出：
# name: Alice
# age: 25
# city: New York
