本文深入探讨了Python中用于创建比萨的函数定义。详细介绍了make_pizza函数如何接受尺寸和配料作为参数，并打印出正在制作的比萨详情。此外，还展示了test_def函数的用法，该函数默认使用'pepperoni'作为配料。文中提供了多种调用这些函数的方法，包括直接导入、使用别名导入以及使用通配符导入。

pizza.py

def make_pizza(size, *toppings):
    print("Making a " + str(size)+ "-inch pizza with the following toppings:")
    for topping in toppings:
        print("- " + topping)

def test_def(size, topping='pepperoni'):
    print("size:"+str(size)+"\ntopping:" + topping)

making_pizza.py

# import pizza
# pizza.make_pizza(16, 'pepperoni')
# pizza.make_pizza(20, 'mushrooms','green peppers', 'extra cheese')

# from pizza import make_pizza
# make_pizza(16, 'pepperoni')
# make_pizza(20, 'mushrooms','green peppers', 'extra cheese')

# from pizza import make_pizza as mp
# mp(16, 'pepperoni')
# mp(20, 'mushrooms','green peppers', 'extra cheese')

# import pizza as p
# p.make_pizza(16, 'pepperoni')
# p.make_pizza(20, 'mushrooms','green peppers', 'extra cheese')

from pizza import *
# make_pizza(16, 'pepperoni')
# make_pizza(20, 'mushrooms','green peppers', 'extra cheese')
test_def(12)
test_def(33,"hello")
