我编写了一个程序来引用日期，从Excel中提取相应的数据，并在网站上输入。
如果有数据，请单击第一个文本字段，输入数据，键入选项卡，然后重复。如果没有任何数据，则单击“无数据”按钮，然后检查下一个日期是否有数据。
在单击“无数据”按钮后调用time.sleep(10)时，代码将按预期工作。
将expected conditions (EC)换成time.sleep(10)时遇到麻烦，特别是在单击“无数据”按钮后尝试输入数据时。
如果在EC语句中为“无数据”调用if，则将连续键入制表符，并且程序将中断。如果在用于输入数据的EC语句中调用else（bx_select()....actionchains(browser)），则不会执行其他代码。
如果调用EC并单击用于单击第一个文本字段的函数，则在第一个文本字段中输入数据，然后键入Tab键，然后返回第一个文本字段。
对如何解决有什么想法？
