获取龙虎榜数据

对于股市来说，那些涨幅跌幅都比较大的股票多是游资的聚集地，这些聚集地往往登上龙虎榜的几率非常的高。对于喜欢玩短期的散户来说，尤其喜欢通过该榜单搏一搏的投资者，尤其钟爱龙虎榜。所以，我们可以给我们的交易软件提供一个这样的榜单。

获取免费龙虎榜的方式如下：

df_rise = ak.stock_sina_lhb_detail_daily(trade_date='20210205', symbol='涨幅偏离值达7%的证券')df_fall = ak.stock_sina_lhb_detail_daily(trade_date='20210205', symbol='跌幅偏离值达7%的证券')

第1个参数如日期，第2个参数为获取的龙虎榜类型。这里，我们的日期都是手动设置的，等我们到后面，通过判断工作日，将其替换掉就行。

pyqt5显示龙虎榜数据

首先，我们需要通过线程获取到龙虎榜的数据，具体代码如下：

import akshare as akfrom PyQt5 import QtCorefrom PyQt5.QtCore import pyqtSignalfrom pandas import DataFrameclass OtherThread(QtCore.QThread):    _signalRise = pyqtSignal(DataFrame)    _signalFall = pyqtSignal(DataFrame)    def __init__(self):        super(OtherThread, self).__init__()    def run(self):        df_rise = ak.stock_sina_lhb_detail_daily(trade_date='20210205', symbol='涨幅偏离值达7%的证券')        df_fall = ak.stock_sina_lhb_detail_daily(trade_date='20210205', symbol='跌幅偏离值达7%的证券')        self._signalRise.emit(df_rise)        self._signalFall.emit(df_fall)

数据获取完成之后，就可以直接显示到界面上了，main.py的代码如下所示：

class MyFrom(QMainWindow):    # 龙虎榜    def init_otherTab(self):        self.otherGrid = QGridLayout()        self.otherGrid.setSpacing(5)        ft = QFont()        ft.setPointSize(26)        ft.setBold(True)        rise_label = QLabel('涨幅偏离值达7%的股票')        rise_label.setFont(ft)        rise_label.setStyleSheet('color:red')        fall_label = QLabel('跌幅偏离值达7%的股票')        fall_label.setFont(ft)        self.otherGrid.addWidget(rise_label, 0, 0, 1, 8)        self.otherGrid.addWidget(fall_label, 0, 8, 1, 8)        self.otherTab.setLayout(self.otherGrid)        self.otherThread = OtherThread()        self.otherThread._signalRise.connect(self.otherRise_callbacklog)        self.otherThread._signalFall.connect(self.otherFall_callbacklog)        self.otherThread.start()    def otherFall_callbacklog(self, df):        ft = QFont()        ft.setPointSize(10)        ft.setBold(True)        m_color = QColor(0, 255, 0)        otherFalltableWidget = QTableWidget(len(df), 6)        otherFalltableWidget.setHorizontalHeaderLabels(['股票名称', '股票代码', '收盘价', '对应值', '成交量', '成交额'])        otherFalltableWidget.setEditTriggers(QAbstractItemView.NoEditTriggers)  #
