基于Python实现新年倒计时
作者:Sir 时间:2022-02-14 08:41:59
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_())
