如何搜索用户输入并找到特定的关键字，然后在文本文件中搜索此关键字？
这就是我目前所拥有的：

foods = str(input("what takeaway would you like today go sir/madame reply with one word answers"))

with open("pizza.txt", "r") as f:              
    searchlines = f.readlines()

for i, line in enumerate(searchlines):      
    if foods in line:  
            print(line)

字符串

python-3.x

你的第一句话意味着你想限制用户输入可能找到的食物。

dishes = (
    "Patriot Pizza: yellow cheese, tomato, olives",
    "Tropical treat: guava cheese, pineapple, mango",
)

foods = ('cheese', 'tomato', 'olives', 'guava', 'pineapple', 'mango')
print(foods)

food = ''
while food not in foods:
    food = input('Enter one of the foods listed above: ')

for i, dish in enumerate(dishes):
    if food in dish:
        print(i, dish)
