Python新年倒计时
不知不觉已经在家两个月了,眼看马上春节就要来临了。满怀期待的写了一个新年倒计时的小工具!
设置新年时间后都能够使用,打开软件后可以自动计算到新年的倒计时情况。
UI界面及布局这块一直使用的是PyQt5来实现的,若是没有安装使用pip的方式安装一下即可。
pip install PyQt5
紧接着将PyQt5以及相关的模块都导入到我们的代码块中准备开发。
# Importing all the classes from the QtWidgets module. from PyQt5.QtWidgets import * # Importing all the classes from the QtGui module. from PyQt5.QtGui import * # Importing the sys module. import sys # It imports all the classes from the QtCore module. from PyQt5.QtCore import * # Importing the datetime module. import datetime # Importing the math module. import math
业务逻辑不是很复杂,我们这次不通过子线程来实现业务逻辑,直接在主线程中开发界面布局和组件以及实现倒计时的过程。
class CountDown(QWidget): def __init__(self): """ A constructor. It is called when an object is created from a class and it allows the class to initialize the attributes of a class. """ super(CountDown, self).__init__() self.spring_date = datetime.datetime(2023, 1, 21, 0, 0, 0) self.init_code() def init_code(self): """ 业务初始化代码块 """ self.setWindowTitle('新年倒计时 公众号:Python 集中营') self.setWindowIcon(QIcon('倒计时.png')) self.resize(600, 400) palette = QPalette() palette.setBrush(QPalette.Background, QBrush(QPixmap("./背景.jpeg"))) self.setPalette(palette) self.timer = QTimer() self.timer.setInterval(1000) self.timer.timeout.connect(self.refresh_count_down) self.timer.start() self.time_label = QLabel() self.time_label.setAlignment(Qt.AlignCenter) self.time_label.setStyleSheet('color:red;font:bold 28px;font-family:黑体') vbox = QVBoxLayout() vbox.addWidget(self.time_label) self.setLayout(vbox) def refresh_count_down(self): """ 刷新页面倒计时时间 """ current_date = datetime.datetime.now() differ_day = (self.spring_date - current_date).days seconds = (self.spring_date - current_date).seconds differ_second = seconds % 60 differ_minute = seconds / 60 % 60 differ_hour = seconds / 60 / 60 if differ_hour > 24: differ_hour = differ_hour - 24 differ_hour = math.floor(differ_hour) differ_minute = math.floor(differ_minute) self.time_label.setText( "距离春节:" + str(differ_day) + "天" + str(differ_hour) + "小时" + str(differ_minute) + "分钟" + str( differ_second) + "秒" + '\r')
使用python模块主函数直接启动春节倒计时桌面应用,就大功告成啦!
# A special variable in Python that evaluates to `True` if the module is being run as the main program. if __name__ == '__main__': app = QApplication(sys.argv) main = CountDown() main.show() sys.exit(app.exec_())
