我正在嘗試制作一個廢棄特定站點資訊但沒有成功的測驗專案。
我遵循了一些我發現的教程，甚至是關于 stackoverflow 的帖子。在這一切之后，我被困住了！
幫幫我，兄弟們，我是 python 的熱門新程式員，我無法停止我的專案。
更多資訊：這是一個彩票網站，我試圖廢棄它并進行一些分析以獲得幸運號碼。
我已遵循本教程：

https://beautiful-soup-4.readthedocs.io/en/latest/
使用 BeautifulSoup 查找所有“ul”和“li”元素
你們都有我的感激之情！
from bs4 import BeautifulSoup as bs
import requests
import html5lib
#import urllib3 # another attemp to make another req in the url ------failed
url = '''https://loterias.caixa.gov.br/Paginas/Mega-Sena.aspx'''
#another try to take results in the <ul> but I have no qualified results == None
def parse_ul(elem):#https://stackoverflow.com/questions/50338108/using-beautifulsoup-in-order-to-find-all-ul-and-li-elements

uj5u.com熱心網友回復：
主要問題是內容是由動態提供的，JavaScript但您可以通過另一個 url 獲取資訊：
jsonData = requests.get('https://servicebus2.caixa.gov.br/portaldeloterias/api/megasena/').json()
會給你JSON以下：
{'tipoJogo': 'MEGA_SENA', 'numero': 2468, 'nomeMunicipioUFSorteio': 'S?O PAULO, SP', 'dataApuracao': '02/04/2022', 'valorArrecadado': 158184963.0, 'valorEstimadoProximoConcurso': 3000000.0, 'valorAcumuladoProximoConcurso': 0.0, 'valorAcumuladoConcursoEspecial': 36771176.89, 'valorAcumuladoConcurso_0_5': 33463457.98, 'acumulado': False, 'indicadorConcursoEspecial': 1, 'dezenasSorteadasOrdemSorteio': ['022', '041', '053', '042', '035', '057'], 'listaResultadoEquipeEsportiva': None, 'numeroJogo': 2, 'nomeTimeCoracaoMesSorte': '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00', 'tipoPublicacao': 3, 'observacao': '', 'localSorteio': 'ESPA?O DA SORTE', 'dataProximoConcurso': '06/04/2022', 'numeroConcursoAnterior': 2467, 'numeroConcursoProximo': 2469, 'valorTotalPremioFaixaUm': 0.0, 'numeroConcursoFinal_0_5': 2470, 'listaDezenas': ['022', '035', '041', '042', '053', '057'], 'listaDezenasSegundoSorteio': None, 'listaMunicipioUFGanhadores': [{'posicao': 1, 'ganhadores': 1, 'municipio': 'SANTOS', 'uf': 'SP', 'nomeFatansiaUL': '', 'serie': ''}], 'listaRateioPremio': [{'faixa': 1, 'numeroDeGanhadores': 1, 'valorPremio': 122627171.8, 'descricaoFaixa': '6 acertos'}, {'faixa': 2, 'numeroDeGanhadores': 267, 'valorPremio': 34158.18, 'descricaoFaixa': '5 acertos'}, {'faixa': 3, 'numeroDeGanhadores': 20734, 'valorPremio': 628.38, 'descricaoFaixa': '4 acertos'}], 'id': None, 'ultimoConcurso': True, 'exibirDetalhamentoPorCidade': True, 'premiacaoContingencia': None}
簡單地提取dezenasSorteadasOrdemSorteio和處理list comprehension：
[n if len(n) < 2 else n[1:] for n in jsonData['listaDezenas']]
結果將是：
['22', '35', '41', '42', '53', '57']
例子
import requests
jsonData = requests.get('https://servicebus2.caixa.gov.br/portaldeloterias/api/megasena/').json()
print([n if len(n) < 2 else n[1:] for n in jsonData['listaDezenas']])
