问题描述
限时送ChatGPT账号..我正在学习如何在 Python 上使用 TinyDB,并且我已经掌握了基础知识(添加、删除、更新等).但现在我正在尝试从数据库中检索特定值.我正在使用的代码是在这个方法中:
I'm learning how to use TinyDB on Python and I have the basics working (add, remove, update etc.). But now I'm trying to retrieve specific values from the database. The code I'm using is in this method:
def showpassword():
show = userdb.get(where("username") == txtname.get())
txtshow.insert(0, show)
当我运行该方法时,它显示如下输出:
When I run the method, it displays the output as follows:
{'username': 'John', 'surname': 'Doe'}
如何才能只显示用户名或姓氏,不带任何括号?
How can I get it so that I can display only the user's name or surname and without any brackets?
推荐答案
TinyDb 将其数据存储为 JSON,在 Python 中表示为字典.
TinyDb stores its data as JSON which is represented in Python as a dictionary.
换行
txtshow.insert(0, show)
到
txtshow.insert(0, "{username} {surname}".format(**show)
查看此处,深入了解字符串格式.
