備忘録：TKinterのEntry＆Label生成と動作をクラス化してコード量を減らした編

Last updated at Posted at 2021-12-16

#はじめに
HCB Advent Clendar 2021の14日目を担当するKimです。
今回は，TKinterでEntryとLabelの生成動作を関数化して，起動時の生成コード量を80%減らした時のことを書きます．
#作業環境

  • Python 3.7.12
  • Tkinter 3.6

##生成画面
GUI_立位動作.png

##生成するUI一覧

  • Label 7個
  • Entry 8個

##生成コード
