Python中的随机配方生成器答案

【问题标题】：Random Recipe Generator in PythonPython中的随机配方生成器

【问题描述】：

我必须在 Python 中创建一个随机配方生成器。以下是设计规范：

至少 25 种不同的食材和 10 种不同的“烹饪短语”可供借鉴。
食谱由成分列表和过程描述组成。该过程应提及列表中的相同成分。
随机生成成分的数量以及成分名称。如有疑问，请以克为单位测量所有内容。
将您的程序组织成函数。您应该至少有 2 个用户定义的函数。

我已经编写了一些代码，但在使用相同的随机生成的成分并将它们添加到“食谱说明”句子的末尾时遇到了问题。

import random

def ingredients_list(quantity, ing):
    quantity = random.choice(amounts)
    ing = random.choice(ingredients)
    return("{} {}".format(quantity, ing))
    
def recipe_instructions(recipe):
    recipe = random.choice(cooking_phrases)
    return("{}".format(recipe))
    
amounts = ["50g", "70g", "90g", "143g", "150g", "180g", "200g", "235g", "300g", "320g", "350g", "386g", "400g", "433g", "462g"]
ingredients = ["eggs", "sugar", "salt", "butter", "milk", "bacon", "tomatoes", "pasta", "rice", "potatoes", "onions", "carrots", "all-purpose flour", "noodles", "cheese", "chicken", "beef", "spinach", "strawberries", "apples", "blueberries", "olive oil", "soy sauce", "corn", "shrimp", "mayonnaise"]
cooking_phrases = ["In a medium sized bowl, whisk together the", "In a large skillet over medium heat, stir-fry the", "In a skillet, Sauté the", "In a large pot, boil the", "Thoroughly wash the", "Thinly slice the", "Make small, 1-inch cubes by dicing up the", "Set the timer for 1 minute and microwave the", "Using a blender, thoroughly blend the",  "For 20 minutes in a 350°F oven, bake the"]


quantity = random.choice(amounts)
ing = random.choice(ingredients)
recipe = random.choice(cooking_phrases)

for i in range(5):
    print(ingredients_list(quantity, ing))

print ("Recipe Instructions:")
for i in range(5):
    print(recipe_instructions(recipe) + " " + ing)

【问题讨论】：

你能比“遇到麻烦”更具体吗？给minimal reproducible example。
您的问题在哪里？你有错误要显示吗？有一些不好的代码实践，您在函数中使用了全局常量（例如random.choice(amounts)）。要么将其作为参数传递给函数，要么明确表示它们是全局常量。
如果能把现在得到的结果和预期的结果都包含进去会更好。

【解决方案1】：

当您使用random.sample() 而不是random.choice() 生成成分时，您会得到一个没有重复的唯一成分列表。请看下面的例子：

import random

def ingredients_list(quantity, ing):
    quantity = random.choice(amounts)
    # ing = random.choice(ingredients) This one can generate duplicates
    return("{} {}".format(quantity, ing))
    
def recipe_instructions(recipe):
    recipe = random.choice(cooking_phrases)
    return("{}".format(recipe))
    
amounts = ["50g", "70g", "90g", "143g", "150g", "180g", "200g", "235g", "300g", "320g", "350g", "386g", "400g", "433g", "462g"]
ingredients = ["eggs", "sugar", "salt", "butter", "milk", "bacon", "tomatoes", "pasta", "rice", "potatoes", "onions", "carrots", "all-purpose flour", "noodles", "cheese", "chicken", "beef", "spinach", "strawberries", "apples", "blueberries", "olive oil", "soy sauce", "corn", "shrimp", "mayonnaise"]
cooking_phrases = ["In a medium sized bowl, whisk together the", "In a large skillet over medium heat, stir-fry the", "In a skillet, Sauté the", "In a large pot, boil the", "Thoroughly wash the", "Thinly slice the", "Make small, 1-inch cubes by dicing up the", "Set the timer for 1 minute and microwave the", "Using a blender, thoroughly blend the",  "For 20 minutes in a 350°F oven, bake the"]

steps = 5

quantity = random.choice(amounts)
ings = random.sample(ingredients, k=steps) # use random.sample to generate unique ingredients and prevent duplicates
recipe = random.choice(cooking_phrases)

for i in range(steps):
    ing = ings[i]
    print(ingredients_list(quantity, ing))

print ("Recipe Instructions:")
for i in range(steps):
    ing = ings[i]
    print(recipe_instructions(recipe) + " " + ing)
