pyqt5图形界面模版，初学pyqt5，经常会用到的代码片段。

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_Form(object):  # 图形界面类
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(300, 150)
        # 文本框
        self.lineEdit = QtWidgets.QLineEdit(Form)
        self.lineEdit.setGeometry(QtCore.QRect(100, 20, 100, 28))  # x坐标,y坐标,宽,高
        self.lineEdit.setObjectName("lineEdit")
        # 按钮
        self.pushButton = QtWidgets.QPushButton(Form)
        self.pushButton.setGeometry(QtCore.QRect(100, 60, 100, 28))
        self.pushButton.setObjectName("pushButton")
        # 标签
        self.label = QtWidgets.QLabel(Form)
        self.label.setGeometry(QtCore.QRect(100, 100, 100, 28))
        self.label.setObjectName("label")

        self.retranslateUi(Form)

    def retranslateUi(self, Form):  # 设置各组件的文本
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "这是一个测试窗口"))
        self.pushButton.setText(_translate("Form", "测试按钮"))
        self.label.setText(_translate("Form", "原文字"))

# 以上是图形界面代码，不用手写。可以用Qt Designer定制，然后用pyuic生成。
#
# ui转py命令：  python -m PyQt5.uic.pyuic xxx.ui -o xxx_ui.py
