我一直在學(xué)習(xí) Python，并想開始我的第一個(gè)項(xiàng)目，我今天完成了對(duì)課程的學(xué)習(xí)，并想繼續(xù)我對(duì)算法的理解，以及我所學(xué)的一切如何結(jié)合在一起。我想這樣做是因?yàn)槲矣X得這些在線資源為您提供了很好的信息，但沒有教太多如何將這些概念應(yīng)用于項(xiàng)目。我想制作一個(gè)簡(jiǎn)單的程序，我可以在其中輸入食譜名稱，并打印成分、烹飪時(shí)間、步驟和名稱。我想使用成分和步驟列表，我想以列表格式打印它們（可能用邊框包裹）。這可能嗎？Class Recipe: def __init__(self, recipe_name, ingredients, cook_time, steps) (self.recipe_name = recipe_name) (self.ingredients = ingredients) (self.cook_time = cook_time) (self.steps = steps)Chicken Noodle = Recipe(Chicken Noodle, [Broth, noodles], 7 minutes, [Bring water to boil, add broth, etc.]

我想你已經(jīng)很接近了！您不需要在構(gòu)造函數(shù)方法中使用這些括號(hào)。我刪除了那些。要打印出整個(gè)配方，我們可以簡(jiǎn)單地使用 to string 函數(shù)。根據(jù)需要更改它：
class Recipe:
def __init__(self, recipe_name, ingredients, cook_time, steps):
self.recipe_name = recipe_name
self.ingredients = ingredients
self.cook_time = cook_time
self.steps = steps
def __str__(self):
output = ''
output += 'Here is the recipe for {}:\n'.format(self.recipe_name)
output += 'You will need: {}\n'.format(self.ingredients)
output += 'This recipe takes: {}\n'.format(self.cook_time)
output += 'Here are the steps involved:\n'
for i, step in enumerate(self.steps):
output += 'Step {}: {}\n'.format(i + 1, step)
return output
你可以運(yùn)行這個(gè)：
chicken_noodle = Recipe('Chicken Noodle', ['Broth', 'noodles'], '7 minutes', ['Bring water to boil', 'add broth'])
print (chicken_noodle)
輸出：
Here is the recipe for Chicken Noodle:
You will need: ['Broth', 'noodles']
This recipe takes: 7 minutes
Here are the steps involved:
Step 1: Bring water to boil
Step 2: add broth
