使用Python PyQt5 vscode 制作流水灯或者交通灯

需要用到 Python PyQt5 vscode，其他的各模块引用在代码里面有，自己找找就行

制作流水灯代码

import sys
from PyQt5.QtCore import (QEvent, QTimer, Qt,QPoint)
from PyQt5.QtWidgets import (QApplication, QMenu,QMainWindow)
from PyQt5.QtGui import QPainter,QPen,QColorclass Widget(QMainWindow):def __init__(self, parent=None):super(Widget, self).__init__(parent)self.text ='hello worlds'self.resize(1200, 800)self.move(100, 100)self.i = 0self.mytimer = QTimer(self)self.mytimer.timeout.connect(self.update)self.mytimer.start(1000)def paintEvent(self,event):painter = QPainter(self)painter.drawEllipse(200,200,160,160)painter.drawEllipse(400,200,160,160) painter.drawEllipse(600,200,160,160)  painter.drawEllipse(800,200,160,160)   painter.drawEllipse(1000,200,160,160) painter.setPen(QColor(255,0,0))painter.setBrush(QColor(255,0,0))if self.i % 5 == 0:painter.drawEllipse(200,200,160,160)elif self.i % 5 == 1:painter.drawEllipse(400,200,160,160) elif self.i % 5 == 2:painter.drawEllipse(600,200,160,160)  elif self.i % 5 == 3:painter.drawEllipse(800,200,160,160)   elif self.i % 5 == 4:painter.drawEllipse(1000,200,160,160) self.i = self.i + 1if self.i > 1000:self.i = 0           if __name__ == "__main__":app = QApplication(sys.argv)form = Widget()form.show()app.exec_()

效果如下

交通灯代码

import sys
from PyQt5.QtCore import (QEvent, QTimer, Qt,QPoint)
from PyQt5.QtWidgets import (QApplication, QMenu,QMainWindow)
from PyQt5.QtGui import QPainter,QPen,QColorclass Widget(QMainWindow):def __init__(self, parent=None):super(Widget, self).__init__(parent)self.text ='hello worlds'self.resize(1200, 800)self.move(100, 100)self.i = 0self.mytimer = QTimer(self)self.mytimer.timeout.connect(self.update)self.mytimer.start(1000)def paintEvent(self,event):painter = QPainter(self)#for i in range(0,11,1):#    painter.drawEllipse(2,2,i,i)if self.i % 3 == 0:painter.setPen(QColor(0,125,0))painter.setBrush(QColor(0,255,0))#painter.drawEllipse(200,200,160,160)elif self.i % 3 == 1:painter.setPen(QColor(255,0,0))painter.setBrush(QColor(255,0,0))#painter.drawEllipse(200,200,160,160) elif self.i % 3 == 2:painter.setPen(QColor(0,0,255))painter.setBrush(QColor(0,0,255))#painter.drawEllipse(200,200,160,160)  painter.drawEllipse(200,200,160,160)painter.drawEllipse(400,200,160,160) painter.drawEllipse(600,200,160,160)  self.i = self.i + 1if self.i > 1000:self.i = 0           if __name__ == "__main__":app = QApplication(sys.argv)form = Widget()form.show()app.exec_()
