从文本文件中检索信息

Question

我想接受用户输入的变量“name”，然后我想将account.zk（这是一个普通的文本文件）加载到一个列表中，然后我想检查输入是否已经在此列表中。如果没有，我想添加它，相反，我想跳过并继续。

我自己编写了这个函数，但没有成功！有人能理解为什么吗？

# Start Downloading System

name = input(Fore.WHITE+"Enter Profile Name To Download: ")

# Save Account (used for check the updates!)

file_object = open("account.zk", "r")

for line in file_object:

  stripped_line = line.strip()

  line_list = stripped_line.split()

  list_of_lists.append(line_list)

if (len(list_of_lists) != len(set(name))):

    print("\n\nAlready in List!\n\n")

    file_object.close

    time.sleep(5)

else:

    file_object.close

    file_object = open("account.zk", "w")

    file_object.write(name + "\n")

    file_object.close

Answer 1

我认为你想做的是以下几点：# Start Downloading Systemname = input(Fore.WHITE + "Enter Profile Name To Download: ")# Save Account (used for check the updates!)file_object = open("account.zk", "r")list_of_lists = []for line in file_object:  stripped_line = line.strip()  line_list = stripped_line.split()  list_of_lists.extend(line_list)  # add the elements of the line to the listif name in list_of_lists:  # check if the name is already in the file    print("\n\nAlready in List!\n\n")    file_object.close()    time.sleep(5)else:  # if not, add it    file_object.close()    file_object = open("account.zk", "w")    file_object.write(name + "\n")    file_object.close()
