Qt Designer设计完是这样的（基本就是16个Push Button和1个lineEdit，再加上尺寸调整以及简单的布局）
设计结束后，保存为name.ui（比如calculator.ui），打开cmd，cd到name.ui所在文件夹，执行以下代码：pyuic5 -o name.py name.ui，生成name.py
打开name.py(比如Spyder)，新建main.py，执行如下代码
import sys from PyQt5.QtWidgets import QApplication, QMainWindow from calculator import Ui_MainWindow class Calcu(QMainWindow, Ui_MainWindow): def __init__(self): super().__init__() self.setupUi(self) self.connection() self.show() def num_0(self): self.lineEdit.insert(‘0‘) def num_1(self): self.lineEdit.insert(‘1‘) def num_2(self): self.lineEdit.insert(‘2‘) def num_3(self): self.lineEdit.insert(‘3‘) def num_4(self): self.lineEdit.insert(‘4‘) def num_5(self): self.lineEdit.insert(‘5‘) def num_6(self): self.lineEdit.insert(‘6‘) def num_7(self): self.lineEdit.insert(‘7‘) def num_8(self): self.lineEdit.insert(‘8‘) def num_9(self): self.lineEdit.insert(‘9‘) def op_plus(self): self.lineEdit.insert(‘+‘) def op_minus(self): self.lineEdit.insert(‘-‘) def op_multiply(self): self.lineEdit.insert(‘*‘) def op_divide(self): self.lineEdit.insert(‘/‘) def op_ce(self): self.lineEdit.clear() def calculate(self): text = self.lineEdit.text() try: self.lineEdit.setText(str(eval(text))) except: self.lineEdit.setText(‘invalid syntax, check your input!‘) def connection(self): self.Num_0.clicked.connect(self.num_0) self.Num_1.clicked.connect(self.num_1) self.Num_2.clicked.connect(self.num_2) self.Num_3.clicked.connect(self.num_3) self.Num_4.clicked.connect(self.num_4) self.Num_5.clicked.connect(self.num_5) self.Num_6.clicked.connect(self.num_6) self.Num_7.clicked.connect(self.num_7) self.Num_8.clicked.connect(self.num_8) self.Num_9.clicked.connect(self.num_9) self.OP_plus.clicked.connect(self.op_plus) self.OP_minus.clicked.connect(self.op_minus) self.OP_multiply.clicked.connect(self.op_multiply) self.OP_divide.clicked.connect(self.op_divide) self.OP_CE.clicked.connect(self.op_ce) self.OP_equal.clicked.connect(self.calculate) if __name__ == ‘__main__‘: app = QApplication(sys.argv) ca = Calcu() sys.exit(app.exec_())
结果如下：
