I’m creating a simple stopwatch on flet (I don’t think it matters) I have a block of code from which I would later like to extract a variable, how do I do this?
<code>import asyncio
import flet as ft
class Stopwatch(ft.Text):
def __init__(self, seconds):
super().__init__()
self.seconds = seconds #here is the variable
def did_mount(self):
self.running = True
self.page.run_task(self.update_timer)
def will_unmount(self):
self.running = False
async def update_timer(self):
while self.seconds >= 0 and self.running:
mins, secs = divmod(self.seconds, 60)
self.value = "{:02d}:{:02d}".format(mins, secs)
self.size = 25
self.weight=ft.FontWeight.W_600
self.update()
await asyncio.sleep(1)
self.seconds += 1 #here is the variable
print(Stopwatch.seconds) #how to get the value?
</code>
<code>import asyncio
import flet as ft
class Stopwatch(ft.Text):
def __init__(self, seconds):
super().__init__()
self.seconds = seconds #here is the variable
def did_mount(self):
self.running = True
self.page.run_task(self.update_timer)
def will_unmount(self):
self.running = False
async def update_timer(self):
while self.seconds >= 0 and self.running:
mins, secs = divmod(self.seconds, 60)
self.value = "{:02d}:{:02d}".format(mins, secs)
self.size = 25
self.weight=ft.FontWeight.W_600
self.update()
await asyncio.sleep(1)
self.seconds += 1 #here is the variable
print(Stopwatch.seconds) #how to get the value?
</code>

self.seconds = seconds #here is the variable

I’m not familiar with flet, but you could create an instance of your class:
<code> sw = Stopwatch(30)
</code>
<code> sw = Stopwatch(30)
</code>
sw = Stopwatch(30)
And then, because it initialized with your __init__() code, you can access the variables in that instance:
<code> print(sw.seconds)
</code>
<code> print(sw.seconds)
</code>
print(sw.seconds)
Whether that works in flet’s development pattern, I’m not sure.
