下面是代碼:Python是混合兩個列表,我不知道爲什麼
import requests
import bs4
response = requests.get('http://discoverygc.com/forums/serverinterface.php?action=players_online') #Loads page
soup = bs4.BeautifulSoup(response.text)
table = soup.find("div", {"id": "forum"})
rowsNo = (str(table).count('<tr>') - 2) #Number of players online. Minus 2 to remove leading title and column description rows
players = systems = [] #Define lists
for i in range(3, (rowsNo + 3)):
rows = table.findAll('tr')[i]
cols = rows.findAll('td')
player = cols[0].get_text()
system = cols[1].get_text()
players.append(player)
systems.append(system)
print(players)
print(systems)
如果我刪除或者players.append(player)
或systems.append(system)
代碼工作正常,輸出正確的列表:
['-Vasqez-', '[-=XTF=-]Neon.Bunny-[R]', "[SV]-Valley'", '<-JohnyWalker->', '~VP)Bad.Tibira', 'Alkanius', 'Apex91', 'Araroba', 'Baldor', 'Benediction', 'Black_Bird', 'Boost', 'Caelius.Moya[X]', 'Core|APM-Maverick', 'Daftwagen', 'Dee.Leers', 'Emiko:Hayashi', 'Gamma-6', 'Gauri', 'Gigi.7', 'GMG|GTS-Komahashi-Maru', 'Grawmod', 'GrazySlon', 'Hunor', 'Jakob-Schleiter', 'Joyita', 'Judge_BigJo', 'JulyJalwa', 'Kruger|KMS-Lankow', 'Luxor', 'monitor91', 'Morgulis', 'Nuggets', 'OSI-Mendes', 'Ronny.Rochester', 'Samura|-Arata', 'Samura|-Ichikawa', 'Shpritzen', 'Stardrifter', 'The_Altair', 'The.Liner.of.Dreams', 'Tony.Sosa', 'Wilde.RNC-Nestor']
或:
['Omega-11', 'Omega-49', 'Pennsylvania', 'Magellan', 'Omicron Gamma', 'Kyushu', 'Pennsylvania', 'Kyushu', 'Omega-5', 'Manchester', 'Cassini', 'Newcastle', 'Connecticut', 'Omega-47', 'Stuttgart', 'Stuttgart', 'Munich', 'New York', 'Hudson', 'Sigma-13', 'Languedoc', 'Colorado', 'Virginia', 'Stuttgart', 'New London', 'Magellan', 'New York', 'New Tokyo', 'Manchester', 'New York', 'Pennsylvania', 'Omega-3', 'Omega-49', 'New Berlin', 'California', 'Nagano', 'New Berlin', 'Okinawa', 'Magellan', 'Texas', 'Ontario', 'New Berlin', 'Stuttgart']
但是,如果我把兩條線都混合在一起的兩個列表:
['-Vasqez-', 'Omega-11', "[SV]-Valley'", 'Omega-49', '<-JohnyWalker->', 'Pennsylvania', '=Z=Exositas', 'Magellan', '~VP)Death.Incarnator', 'Omicron Gamma', 'Alkanius', 'Shikoku', 'Apex91', 'Pennsylvania', 'Baldor', 'Kyushu', 'Benediction', 'Omega-5', 'Black_Bird', 'Manchester', 'Boost', 'Cassini', 'Caelius.Moya[X]', 'Connecticut', 'Core|APM-Maverick', 'Omega-47', 'Daftwagen', 'Stuttgart', 'Darf.Acour', 'Texas', 'Dee.Leers', 'New Berlin', 'Emiko:Hayashi', 'Munich', 'Gamma-6', 'New York', 'Gauri', 'Hudson', 'Gigi.7', 'Orkney', 'GMG|GTS-Komahashi-Maru', 'Colorado', 'Grawmod', 'Virginia', 'GrazySlon', 'Stuttgart', 'Hunor', 'Manchester', 'Jakob-Schleiter', 'New Berlin', 'Joyita', 'Magellan', 'Judge_BigJo', 'New York', 'Kruger|KMS-Lankow', 'New Tokyo', 'Luxor', 'Manchester', 'monitor91', 'New York', 'Morgulis', 'Pennsylvania', 'Nuggets', 'Omega-3', 'OSI-Mendes', 'Omega-49', 'Ronny.Rochester', 'California', 'Samura|-Arata', 'Nagano', 'Samura|-Ichikawa', 'New Berlin', 'Stardrifter', 'Okinawa', 'The_Altair', 'Magellan', 'Tony.Sosa', 'Ontario', 'Wilde.RNC-Nestor', 'Omega-7']
這是爲什麼?我看不出爲什麼會發生這種情況。
'玩家=系統= []'意味着它們是相同的列表。如果你想要一個單線程玩家,系統= [],[]'。或者你可以把它分成兩行。 –
