Kivy: how to access widget's id defined in KV lang using string in Python code
Kivy allows to use .ids["name"]
instead of .ids.name
And this allows to use string formatting to create string with name
.ids[f"label_{i}"].text
.ids["label_{}".format(i)].text
.ids["label_%s" % i].text
In documentation Accessing Widgets defined inside Kv lang in your Python code you can see example code with comment "alternative syntax"
self.ids.hulk.text = "hulk: puny god!"
self.ids["loki"].text = "loki: >_<!!!" # alternative syntax
ids
is dictionary type property and you can iterate it
for key, val in self.ids.items():
print("key={0}, val={1}".format(key, val))
