如何在 Python 中为每个 ID 打印到 .csv

Question

import urllib
import re
import csv
player_code = open("Desktop/OHL PYTHON/test2.txt").read()
player_code = player_code.split("r")
for pc in player_code:
    htmlfile = urllib.urlopen( "http://www.eliteprospects.com/iframe_player_stats_small.php?player="+pc+"")
    htmltext = htmlfile.read()  
    regex = '<font color="#000099">(.+?)</font>'  
    pattern = re.compile(regex)
    team = re.findall(pattern,htmltext)
    data = pc, team

    with open('my_games.csv', 'w') as csvfile:
        fieldnames = ['pc', 'team','League', 'Gp', 'G','A','P','Pims']
        writer = csv.DictWriter(csvfile, fieldnames=fieldnames,delimiter= ":",
                                extrasaction ='ignore')
        i=0
        writer.writeheader()
        for pc in player_code:
            writer.writerow({'pc':[pc],'team':[team]})
            i+=1

这只是一遍

又一遍地返回一行数据。任何方向都会有所帮助！谢谢。

Answer 1

您应该在 for 循环之前打开文件或使用a+模式。 w打开文件并在每次打开时截断其数据。

with open('my_games.csv', 'w') as csvfile:
    for pc in player_code:

或

with open('my_games.csv', 'a+') as csvfile

打开文件一次会是更好的方法。

由于您循环两次以写入数据，因此您有多行。只需删除

i=0
for pc in player_code:
    writer.writerow({'pc':[pc],'team':[team]})
        i+=1

相反，只要拥有，我认为它会起作用。

writer.writerow({'pc':[pc],'team':[team]})
