Ich fange gerade an, in Python zu programmieren, und ich verwende es, um ein kleines Programm mit einer GUI (mit tkinter), die Daten aus nehmen kann eine Excel-Datei (mit openpyxl). Lassen Sie den Benutzer bei Bedarf Dinge ändern und verwenden Sie dann eine Schaltfläche, um die Daten aus den Einträgen in eine Datendatei (.dat) zu schreiben (vorzugsweise durch Aktualisieren der Werte in den defaultdict-Arrays und dann in die .dat-Datei) und eine Modellierungssprache zu verwenden (pyomo), um ein Modell mit den bereitgestellten Daten zu erstellen und es mit dem cbc-Solver zu lösen.Python> tkinter: Wie bekomme ich Werte von einem Panel in einem Notebook-Rahmen
Ich bin jetzt sofar, dass ich das Modell, die grafische Schnittstelle (die mit Daten aus der Excel-Datei gefüllt ist) gemacht habe. Allerdings kann ich die Daten in den Eingabefeldern nicht zurückholen (um die defaultdict Arrays zu schreiben). Ich verstehe die einfachen Beispiele auf stackoverflow (mit entry.get()), aber es hat bei meinem Beispiel nicht funktioniert (wahrscheinlich, weil ich Tabs, Panels und Frames von notbook verwende oder etwas vermasselt habe).
Ich benutze Notebook Tabs statt einer Seite, weil ich mehr (etwa 5) andere Kategorien von Daten in dem vollständigen Programm haben werde. Endlich möchte ich das Programm so gestalten, dass es sich an die Eingabe anpassen kann (es weiß also nicht, ob es 3, 8 oder 10 Möglichkeiten geben wird). Ich benutze Python Version 3.5.1. Hier ist der Link zu der Excel-Datei: https://drive.google.com/file/d/0B5vmtJnltudJWW4xakZlYnQ3RTg/view?usp=sharing
