如何减少 python 中嵌套循环的时间
how to reduce the time of a nested loop in python
我正在从ESPN获取球员数据，但我发现自己的问题是获取每个变量等待时间很长，如何提高效率？
players_by_temp = []
for i in range(20):
players = []
for j in range(len(html_table[i].find_all(class_='AnchorLink'))):
players.append(html_table[i].find_all(class_='AnchorLink')[j].text)
players_by_temp.append(players)
print(i)
players_by_temp = []
for i in range(20):
players = []
for anchor in html_table[i].find_all(class_='AnchorLink'):
players.append(anchor.text)
players_by_temp.append(players)
print(i)
一旦您对 Python 感到更舒服，您就可以将三个中心线替换为以下内容：
players = [anchor.text for anchor in html_table[i].find_all(...)
