Pyqt5初步(1)——一个计算器
弄了个Pyqt5 也是python GUI的一种不得不说功能是真的强大
还有 为了每次新建一个项目不那么麻烦，我还写了一个create.py也贴在这里吧 放在最后 把创建项目重复的部分都自动创建了
这是个计算器
emmm本来是昨天写完的但是太晚了就没发出来...而且忘加小数点了
我是用的Qt Designer来布置
创建的是widdget

with open(path_new+'\\'+'click_me.bat','w') as f:
f.write('pyuic5 -o {}.py {}.ui'.format(name2,name2))
然后那个create.py就是双击之后回答三个问题 之后自动创建文件夹和两个文件 用Qt designer的话把.ui文件保存到这个文件夹里（.ui文件名要和你回答的第二个问题一样）
然后双击click_me.bat，等编译完成再双击main.py就可以运行了 python就是GUI麻烦 不错，学习了。 Pyqt 看界面怎么像Python，学习了。 学习了，谢谢分享。 thank you for your resources ！ 棒棒棒~~~ 下来，学习
