弘扬奥运精神，我们49行画个奥运五环｜Python 主题月

本文正在参加「Python主题月」，概况检查 活动链接

xdjmm，我仍是那只不守妇道的花喵。

虽然这届奥运遇到重重阻止，疫情影响而延迟，延迟了要举办民众仇视，再然后排演后还爆出xq案子，更有小道爆出内情。这些种种咱们就忽略掉吧～

截止本文发表，咱们看看战况：

宏扬奥运精力，今天咱们用49行写歌奥运五环～

本文作用预览：

奥林匹克标志

奥林匹克 标志(Olympic Logo /Symbolgooglee Olympique/Olympic Rings)是由皮埃尔德顾拜旦先生于1913年构思规划的，是由《奥林匹克宪python能够自学吗章》供认的，也被称为奥运五环标志，它是国际范围内最为人们广泛认知的奥林匹克运动会标志。它由5个奥林匹克环套接组成APP，有蓝、黄、黑、绿、红5种色彩。环从左到变量与函数右相互套接，变量与函数上面是蓝、黑、红环，下面是是黄、绿环。整个造形为一个底部小的规矩梯形。

初始化

咱们使用的是PyQt5

先搭个框架：

import sys
from Py变量值Qt5.QtapproachGui import QPainter, QPen, QBrush
from PyQt5.QtWidgeappearancets impo变量的界说rt QWidget, QApplication
from PyQt5.QtCore import Qt
# 界说Olympic类
class Olympic(QWidget):
def __init_变量英文_(self):变量之间的联系
# 父类初始化
super().__init__()
# 设置宽高
self.setGeometry(300, 300, 550, 6python怎样读00)
sappearanceelf.setWindowTitle('奥运五环')
# 初始化变量
self.isBlue = False
self.isYellow = False
self.isBlack = False
self.isGr狗狗币een = False
self.isRed = False
self.brusappearhWidth = 10
self.show()
# 界说粉刷作业
def变量泵 paintEven工程造价t变量类型有哪些(self, event):
qp = QPainter()
qp.begin(self)
if __nampython编程e__ == '__main__':
app = QApplication(sys.argv)
ex = Olympic()
app.exec_()

开始

先粉刷第一个python培训班学费一般多少蓝色圈圈

  # 界说粉刷作业
def paintEvent(self, event):
qp = QPainter()
qp.begin(s工程造价elf)
bluePen = QPen(QBrush(Qt.blue), self.brushWidth)
qp.setPen(bluePen)
qp.drawEllipse(99, 150, 100, 100)
qp.end()

依次画出其他色彩的圈圈

  # 界说粉刷作业
def paintEvent(self, event):
q变量类型有哪些p = QPainter()
qp.begin(self)
bluePen = QPengoogle(QBrush(Qt.blue), self.brushWi变量之间的联系dth)
yellowPen = QPen(QBrush(Qt.yellow), sappleelf.brushWidth)
blackPen = QPen(QBrush(Qt.black), self.brushWi变量英文dth)
greenPen = QPen(QBrush(Qt.green), self.brushWapp下载idth)
redPen = QPen(QBrush(Qt.red), self.brushWidth)
qp.setPen(bluePen)
qp.drawEllipse(99, 150, 100, 100)
qp.setPen(yellowPen)
qp.drawEllipse(161.5, 200, 100, 100)
qp.setPen(blpython是什么意思ack宫颈癌前期症状Pen)
qp.drawEllipse(224, 150, 100, 100)
qp.setPenappointment(greenPen)
qp.drawEllipse(286.5, 200, 100, 100)
qp.setPen(redPen)
qp.drawEllipse(349, 150, 100, 100)
qp.end()

画python爬虫完是这变量是什么意思样婶的～

优化环环相扣

你以为画完了？

nono～

奥运五环时这样婶的～

伦家是环环相扣的

所以咱们要处理下，先画个试试：

    # 画个圆弧覆盖下
qp.setPen(bluePen)
qp.drawArc(99, 150, 100, 100, 345*16, 30*16)

看下作用

黄色和蓝色是对了，咱们再用相同的方式处理下

    # 画个圆弧覆盖下
qp.setPen(bl变量是什么意思uePen)
qp.dr变量是什么意思awArc(99, 150, 100, 1APP00, 345*16, 30*16)
qp.setPen(yellowPen)
qp.drawArc(16python123渠道登录1.5, 200, 100, 100, 70*16, 15*16)
qp.se变量泵tPen(greenPen)
qp.drawArc(286.5, 200, 100, 100, 1appearance60*16, 30*16)
qp.setPen(blackPen)
qp.drawArc(224, 150, 100, 100, 345*16, 30*16)
qp.setPenPython(greenPen)
qp.drawArc(286.5, 2python怎样读00, 100, 100, 70*16, 15*16)
qp.end()

看下作用

这样咱们的奥运五坏就画完了～

不过这样如同太python能够自学吗简略了，咱们加个鼠标点击圈圈来取色，假设两个变量色彩的圈圈穿插咱们要取出狗狗币两种色彩，预备备，开始～

取色

Olympic类添加界说鼠标点击作业

  # 界说鼠标点击作业
def mousePressEvent(self, event):
self.x = evenappointmentt.x()
self.y = event.y()
# 依据鼠标方位核算是否点击在圈圈内
def point_is_in_the_circle(origin_x, origin_y, radius, x, y):
