在python中如何在函数中修改列表

首先定义一个函数，此函数用途是将unprinted_designs中的元素添加到complete_models中去

def print_models(unprinted_designs, complete_models):
    while unprinted_designs:
        current_design = unprinted_designs.pop()
        print(f"Printing model:{current_design}")
        complete_models.append(current_design)
        while unprinted_designs==[]:
            break

然后再定义一个函数，此函数的用途是将complete_models中的元素打印出来

def show_complete_models(complete_models):
    print("\nThe flowing models have been printed:")
    for complete_model in complete_models:
        print(complete_model)

定义两个列表，有一个列表为空列表

unprinted_designs = ['phone case', 'robot pendant', 'dodecahedron']
complete_models = []

调用函数

print_models(unprinted_designs[:], complete_models)
show_complete_models(complete_models)

结果如下
