尝试让AI正确调用文本文件中的集合名称

Question

从字面上看，一切都很正常。我只是想在她读用户名的时候不让括号显示出来。我自己尝试了很多方法，但似乎都不起作用。有人能帮上忙吗？我的问题在except块中的readline上

try:
    mem_recall=open('ai_memory.txt', 'x')
    mem_recall.close()
    print('Hi there. My name is Alice. What\'s yours?')
    u_name=input('Enter your name: ')
    mem_recall=open('ai_memory.txt', 'w')
    mem_recall.write('Username: '+str(u_name))
    mem_recall.close()
    mem_recall=open('ai_memory.txt', 'r')
    u_name=mem_recall.readlines(1)
    mem_recall.close()
    u_name=str(u_name).replace('Username: ', '')
    input('Welcome, '+str(u_name)+'.')
except:
    mem_recall=open('ai_memory.txt', 'r')
    u_name=mem_recall.readlines(1)
    mem_recall.close()
    u_name=str(u_name).replace('Username: ', '')
    print('Welcome back, '+str(u_name)+'.')
    sleep(0.5)
    print('Today is '  + str(datetime.datetime.strptime(str(datetime.date.today()), '%Y-%m-%d').strftime('%m.%d.%Y')) + '.')

你在给readlines打电话

u_name=mem_recall.readlines(1)

这将返回行的列表。

然后显式地请求该列表的字符串表示：

u_name=str(u_name).replace('Username: ', '')

列表的字符串表示形式如下所示：

['this is the actual line here, inside quotes and brackets']

如果你不想那样做，那就不要那样做。如果只想要一行代码，请调用readline，而不是readlines

u_name = mem_recall.readline()
u_name = u_name.replace('Username: ', '')
