Question

如何根据用户输入从csv文件运行特定行。我的代码要求用户用手机输入问题，如果用户输入的水溢出了关键字water或溢出将被识别，并且将打印存储在csv中的解决方案。但是我在那里为不同的关键字存储了许多解决方案。

Answer 1

如果您的问题/解决方案以这种方式写入文件：

Problems1\nSolution1\nProblems2\nSolution2

给出：

Problems1
Solution1
Problems2
Solution2

你可以试试这段代码：

problem = input ('What is your problem ? ')

with open ('keywords.txt', 'r') as myfile:
    text = myfile.read()

list_of_problems_and_solutions = text.split('\n')

for i in range (0, len(list_of_problems_and_solutions )-1, 2):
    if problem in list_of_problems_and_solutions [i]
    print (list_of_problems_and_solutions [i + 1])

>>> What is your problem ? Problems1
Solution1

list_of_problems_and_solutions会像['Problems1', 'Solution1', 'Problems2', 'Solution2' ]一样 for i in range (0, len(list_of_problems_and_solutions )-1, 2):函数将遍历从索引0到结尾的列表，步长为2。如您所见，当我输入Problems1作为我的问题时，Python返回Solution1。您只需要替换为您的关键字/解决方案

Answer 2

首先将数据集重写为：

'turn', 'on', 'off'
put it on charger
'small', 'text'
go on settings.
...

然后搜索问题并打印下一行。

problems = input("What is the problem?")

with open("/path/myfile.csv") as myfile:
    file = iter(myfile.readlines())
    for line in file:
        if any(word in line for word in problems.split()):
            print(next(file))
            break
