tkinter messagebox 中的格式化方法
Format method in tkinter messagebox
我想 return 使用 Python 3 中的 .format() 方法计算某个数值,并在其中使用 div 运算符(/ ).
但是消息框库不支持此功能。
#Remind dilutions
if self.initial_concentration > (1000):
messagebox.INFO('Since your dilution is in the lowest range, consider a 1:100 pre-dilution first, so you would have {:2f}').format(answer)
你知道我该如何克服这个问题吗?
谢谢
messagebox.INFO('Since ... have {:2f}').format(answer)
# ^
# calling `format` method of the return value of the `INFO(..)`,
# (not against the formatting string)
# which may not exists; possibly causing AttributeError
以上行应替换为:
messagebox.INFO('Since ... have {:2f}'.format(answer))
format
是一个 str 函数,您应该从 str 而不是 INFO 使用它。
解决方案:
messagebox.INFO('Since your dilution is in the lowest range, consider a 1:100 pre-dilution first, so you would have {:2f}'.format(answer))
