python-3.x - 空值到空值 JSON 在嵌入中发送

问题描述

我正在发出一个命令，它会随机吐出要制作的饮料。问题是，一些饮料比其他饮料有更多的成分和测量值，这导致一些键返回为 null 或 None。我fix_data过去常常将 Nones 变成空白，但这会在我的嵌入中造成巨大的差距。有没有更简单的方法来显示嵌入中的数据或更简单的方法来清除 JSON 中的 None 值？

def fix_data(data):
    if type(data) is list:
        for i, e in enumerate(data):
            if e is None:
                data[i] = ''
            else:
                fix_data(e)

 if message.content.lower().startswith("!drink"):
        url = 'https://thecocktaildb.com/api/json/v1/1/random.php'
        res = requests.get(url)
        data = res.json()
        fix_data(data)
        drinkname = data['drinks'][0]['strDrink']
        drinkimage = data['drinks'][0]['strDrinkThumb']
        instructions = data['drinks'][0]['strInstructions']
        ingredient1 = data['drinks'][0]['strIngredient1']
        ingredient2 = data['drinks'][0]['strIngredient2']
        ingredient3 = data['drinks'][0]['strIngredient3']       
        ingredient4 = data['drinks'][0]['strIngredient4']
        ingredient5 = data['drinks'][0]['strIngredient5']
        ingredient6 = data['drinks'][0]['strIngredient6']
        ingredient7 = data['drinks'][0]['strIngredient7']

解决方案

使用 for 循环和 if 语句检查每种成分是否为无。

import requests

url = 'https://thecocktaildb.com/api/json/v1/1/random.php'
res = requests.get(url)
data = res.json()

drinks = data['drinks'][0]
ingredients_list = ""

for i in range(1, 16):
    if drinks[f"strIngredient{i}"]:
        measure = drinks[f"strMeasure{i}"]
        ingredient = drinks[f"strIngredient{i}"]
        ingredients_list+=f"{measure if measure else ''} {ingredient}\n"

drinkname = drinks['strDrink']
drinkimage = drinks['strDrinkThumb']
instructions = drinks['strInstructions']

msg = f"**Drink**:\n {drinkname}\n\n **Ingredients**:\n {ingredients_list}\n **Instructions**: \n{instructions}"

print(msg)
