[英]How can I simplify code with f“{}” Python
I want to simplify my code, I did it via f"{}".我想简化我的代码,我是通过 f"{}" 完成的。 But now I need when you click on certainly item, to switch a screen with certain number.但是现在我需要当你点击确定项目时,切换一个具有特定数字的屏幕。 But I don't know how.但我不知道怎么做。 Are there any possibilities?有没有可能?
def show_bottom_sheet(self):
bs = MDListBottomSheet()
bs.add_item("bla bla", lambda x: x,icon='account-group-outline')
for y in 1,2,3,4,12,13:
bs.add_item(f"number {y} ", lambda x: self.behavior(), icon='account-group-outline'.format(y))
bs.open()
instead of代替
#bs.add_item("2", lambda x: self.behavior2(), icon='account-group-outline')
#bs.add_item("3", lambda x: self.behavior3(),icon='account-group-outline' )
#bs.add_item("4", lambda x: self.behavior4(),icon='account-group-outline' )
#bs.add_item("12", lambda x: self.behavior12(),icon='account-group-outline' )
#bs.add_item("13", lambda x: self.behavior13(), icon='account-group-outline')
I tried something like this but unsuccessful:我尝试过这样的事情但没有成功:
def behavior(self):
for y in 1, 2, 3, 4, 12, 13:
self.manager.current = f"{y}"
I had it before like this我以前有过这样的
def behavior2(self):
self.manager.current = "2"
def behavior3(self):
self.manager.current = "3"
def behavior4(self):
self.manager.current = "4"
def behavior12(self):
self.manager.current = "12"
def behavior13(self):
self.manager.current = "13"
def behavior14(self):
I think that your behavior()
method needs to take a parameter:我认为您的behavior()
方法需要带一个参数:
bs.add_item(f"number {y} ", lambda x: self.behavior(x), icon='account-group-outline'.format(y))
...
def behavior(self, x):
self.manager.current = f"{x}"
