【Week4.2】第八章（函数）

#8-7不太理解为什么打印出来的字典的键值对顺序和创建时的顺序不同，singer和album之间的顺序有点奇怪；
#8-8：这一题由于缩进错误，其实是逻辑上的问题，导致一开始没能顺利打印出正确的结果；
#8-15使用import的时候感觉命名很重要，可能因为命名原因，而无法正确运行；

	print("The usage of function in python.")

		completed_models.append(current_design)

def show_completed_models(models):
	print("\nThe following models have been printed:")
	for completed_model in models:
		print(completed_model)

直接导入文件：

#import printing_functions
unprinted_designs = ['iphone case', 'robot pendant', 'dodecahedron']
completed_models = []
printing_functions.print_models(unprinted_designs, completed_models)
printing_functions.show_completed_models(completed_models)

导入文件中的函数：

from printing_functions import print_models, show_completed_models
unprinted_designs = ['iphone case', 'robot pendant', 'dodecahedron']
completed_models = []
print_models(unprinted_designs, completed_models)
show_completed_models(completed_models)

导入文件中函数模块并重新命名：这里多个模块一起命名会出错，也许只有分开命名才行！

from printing_functions import print_models as pm
from printing_functions import show_completed_models as scm
unprinted_designs = ['iphone case', 'robot pendant', 'dodecahedron']
completed_models = []
pm(unprinted_designs, completed_models)
scm(completed_models)

导入文件并重新命名：

import printing_functions as pf
unprinted_designs = ['iphone case', 'robot pendant', 'dodecahedron']
completed_models = []
pf.print_models(unprinted_designs, completed_models)
pf.show_completed_models(completed_models)

导入文件所有的模块：在这里可以直接使用函数

from printing_functions import *
unprinted_designs = ['iphone case', 'robot pendant', 'dodecahedron']
completed_models = []
print_models(unprinted_designs, completed_models)
show_completed_models(completed_models)
