python - How to pass an argument to event handler in tkinter? -

- 

  widget.bind ('& lt; बटन-1 & gt;', कॉलबैक) # बाध्यकारी def कॉलबैक (स्वयं, घटना ) #do कुछ

मुझे कॉलबैक () पर तर्क देने की आवश्यकता है। तर्क एक शब्दकोश वस्तु है।

आप किसी अनाम फ़ंक्शन को परिभाषित करने के लिए उपयोग कर सकते हैं, जैसे: 

  डेटा = {"एक": 1, "दो": 2} widget.bind ("& lt; बटन दबाएं;", लैम्ब्डा इवेंट, arg = डेटा: self.on_mouse_down (ईवेंट, arg ))

ध्यान दें कि पास में arg सिर्फ एक सामान्य तर्क है कि आप अन्य सभी तर्कों की तरह उपयोग करते हैं: 

  Def on_mouse_down (स्वयं, ईवेंट, आर्ग): प्रिंट (आर्ग)

For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
