如何在简单的 Kivy 应用程序中将 Pandas 数据框显示为表格？

Question

我想构建一个简单的 Kivy 应用：

1. 要求用户输入一个整数 (MTP)
2. 要求用户输入延迟间隔（delay）
3. 在用户按下提交按钮后查询一个url，然后从 该查询创建一个显示的熊猫数据框（如 表）在 Kivy 应用程序的主屏幕上，然后输出 更新数据帧，直到 MTP 和延迟间隔结束

我将查询的所有代码用作常规 python 程序，我只是不知道如何显示用户输入和输出数据帧（和时间戳）。 （见下文）

import requests
import time
from bs4 import BeautifulSoup
from datetime import datetime
import itertools
import pandas as pd

mtp = input("Input whole number of minutes to post:") #<-How to do on Kivy Screen
delay = input("Enter 15, 30 or 60 second delay:") #<-How to ask on Kivy Screen
STP = int(mtp)*60

def requestOdds():
    url = "https://WEBPAGE WITH ODDS DATA.aspx"
    r = requests.get(url)
    soup = BeautifulSoup(r.content)
    stamp = datetime.now().strftime('%m/%d %H:%M:%S')
    tbPPosts = ('rptOdds_ctl01_tdOdd', 'rptOdds_ctl02_tdOdd','rptOdds_ctl03_tdOdd','rptOdds_ctl04_tdOdd','rptOdds_ctl05_tdOdd','rptOdds_ctl06_tdOdd','rptOdds_ctl07_tdOdd','rptOdds_ctl08_tdOdd','rptOdds_ctl09_tdOdd','rptOdds_ctl10_tdOdd','rptOdds_ctl11_tdOdd','rptOdds_ctl12_tdOdd','rptOdds_ct113_tdOdd','rptOdds_ct114_tdOdd','rptOdds_ct115_tdOdd','rptOdds_ct116_tdOdd','rptOdds_ct117_tdOdd','rptOdds_ct118_tdOdd','rptOdds_ct119_tdOdd','rptOdds_ct120_tdOdd','rptOdds_ct121_tdOdd')
    mlPPosts = ('rptOdds_ctl01_tdMl','rptOdds_ctl02_tdMl','rptOdds_ctl03_tdMl','rptOdds_ctl04_tdMl','rptOdds_ctl05_tdMl','rptOdds_ctl06_tdMl','rptOdds_ctl07_tdMl','rptOdds_ctl08_tdMl','rptOdds_ctl09_tdOdd','rptOdds_ctl10_tdMl','rptOdds_ctl11_tdMl','rptOdds_ctl12_tdMl','rptOdds_ct113_tdMl','rptOdds_ct114_tdMl','rptOdds_ct115_tdMl','rptOdds_ct116_tdMl', 'rptOdds_ct117_tdMl','rptOdds_ct118_tdMl','rptOdds_ct119_tdMl','rptOdds_ct120_tdMl','rptOdds_ct121_tdMl')
    trimmed_text=[]
    trimmed_text2=[]
    tbodds = []
    mlodds = []
    odds = []

    for horse in tbPPosts:
        table = soup.find('td', {"odds-table-odd"}, id=horse)
        if table is not None:
            text = table.renderContents()
            trimmed_text = text.strip()
            tbodds.append(trimmed_text) 

    for mlhorse in mlPPosts:
        table2 = soup.find('td', {"odds-table-ml"}, id=mlhorse)
        if table2 is not None:
            text2 = table2.renderContents()
            trimmed_text2 = text2.strip()
            mlodds.append(trimmed_text2)

    mlodds = itertools.ifilterfalse(lambda x: x=='', mlodds) #faster
    tbodds = itertools.ifilterfalse(lambda x: x=='', tbodds)
    oddsDict = dict(zip(mlodds, tbodds))
    **odds = pd.DataFrame(list(oddsDict.iteritems()), columns=['ML','TB'])
    print odds, stamp** #<--How do I get these to print onto the Kivy Screen?

def getLiveOdds():
    interval = 0
    while interval <= STP:
        requestOdds()
        time.sleep(delay)
        interval +=delay

getLiveOdds()

任何帮助将不胜感激！

我发现了一些可以帮助你的东西：

基维文件

GraphDraw:

<GraphDraw>:

    BoxLayout:
        Button:
            text: "Hello World"
            on_press: root.graph()

逻辑

#!/usr/bin/env python
# -*- encoding: utf-8

import datetime
import pandas as pd
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
import dfgui
import pandas as pd


class Visualisation(App):
    pass

class GraphDraw(BoxLayout):
    def graph(self):
        xls = pd.read_excel('filepath')
        #df = pd.DataFrame.xls
        dfgui.show(xls)
        #print xls

if __name__ == '__main__':
    Visualisation().run()

所以您使用 dfgui 可以创建 pandas 数据框表，而不是使用 Kivy。 查看项目 dfgui：https://github.com/bluenote10/PandasDataFrameGUI
