How do I bind the ENTER key to it? I tried doing:

但我得到未解决的参考错误..

but I get unresolved reference error..

def showLDAPMembers(yourName,yourPassword):

推荐答案

如果要传递参数，则需要使用 lambda.

You need to use a lambda if you're passing arguments.

app.bind("<Return>", lambda x: showLDAPMembers(yourName,yourPassword))

bind 命令会自动返回调用它的事件，因此您需要定义并丢弃它(使用 lambda x:)

The bind command automatically returns the event that called it, so you need to define and throw away that (with lambda x:)
