df= pd.read_csv('test.csv')
df["Name"] = df["Infraction"] = df["Yards"] = ""
df[["Name", "Infraction", "Yards"]] = map(df.Detail.apply(extract))
这是下面的示例条目。
val = 'Kirk Cousinspass complete short left toJamison Crowderfor 33 yards (tackle byDamontre Moore). Penalty onKory Lichtensteiger: Offensive Holding, 10 yards'
我有以下代码。
df[["Name", "Infraction", "Yards"]] = list(df.Detail.apply(extract))
我有一个我创建的提取方法。
def extract(entry):
split = entry.split(':')
sliced = entry.index('Penalty on')
new_phrase = entry[sliced:]
name_index = new_phrase.find(':')
name = new_phrase[:name_index]
second_part = new_phrase[name_index:]
infraction = second_part.split(',')[0].split(':')[1].strip()
yards_penalized = second_part.split(',')[1].strip()
return name[10:], infraction, yards_penalized
我很确定这段代码不是最好的方法，但即便如此我也收到了这个错误。
line 8, in extract
sliced = entry.index('Penalty on')
ValueError: substring not found
我知道这就是轰炸。我试过用try，catch。可能是错误的，现在就陷入困境。谢谢！
