Question

如何在程序中输入大小写混合的单词，以便它读取CSV文件并打印正确的解决方案？

在这种情况下，我希望这样，当用户输入mY sOuNd Is BrOkEn时，读者会选择sound关键字并打印链接的回复。

problem=input("\nWhat problem do you have with your phone?\n\n ")
#Prints 'What problem do you have with your phone?' and expects an answer in the CSV file.
space=problem.split(" ")
#Splits their response into a list for each word used.
openfile=csv.reader.lower()(open("task2.csv"))
#Opens task2 file and creates a CSV Reader for it.
read=[row for row in openfile]
#Outputs the information from the CSV into a 2D list.

for x in range(0,len(space)):
    #Loops through the user input
    for y in range(0,len(read)-1,2):
            #Loops through each row in the CSV.
        if (space[x] in read[y]):
            #Checks if the current word is in the current row of the list.
            print(read[y+1][0])
            #Prints a link to your response.
            print("\nThank you for using GetRekt Troubleshooting.\n")
            #Prints 'Thank you for using GetRekt Troubleshooting.'
        elif problem==("Exit"):
            print('You have decided to terminate the program. Goodbye.')
            sys.exit(0)
        else:
            continue
            restart()

在这里，.lower（）函数不起作用。请帮忙！

Answer 1

在您当前的示例中，read[y]对应一行。这意味着read[y]不是字符串，而是表示行的list对象。

您需要将read定义为：

read=[[field.lower() for field in row] for row in openfile]

这样您就可以在每行中的每个元素上运行lower()。

现在只需检查关键字是否在一行中：

if (space[x].lower() in read[y]){
    ...
}

Answer 2

如果在正确的变量上执行，

lower()将起作用。不应在csv.reader.lower()(open("task2.csv"))上执行它，而应该对字符串变量执行。

示例：

# open using csv reader
openfile = csv.reader("task2.csv", delimiter=',', quotechar='"')

...

# compare strings using lower()
if (space[x].lower() in read[y].lower()):
    ...
