我正在處理來自Kaggle的數據集,並且想要提取帶有名稱的Pandas列的標題。我使用下面的代碼:錯誤:無法將參數轉換爲Python中的整數
def extract_patt(patt, linea):
matchObj = re.match(patt, linea)
result = ""
if matchObj:
return matchObj.group(1).lower()
else:
return ""
def extract_title(linea):
return extract_patt('^.+,\s(.+)\..+', linea)
titles = dataframe1["Name"].apply(extract_title)
title_mapping = {"": 0, "mr": 1, "miss": 2, "mrs": 3, "master": 4, "dr": 5, "rev": 6, "major": 7, "col": 7, "mlle": 8, "mme": 8, "don": 9, "lady": 10, "countess": 10, "jonkheer": 10, "sir": 9, "capt": 7, "ms": 2}
for k in title_mapping:
titles[titles == k] = title_mapping[k]
dataframe1["Title"] = titles
然而,當我在Azure上機運行這段代碼的學習平臺作爲一個Python代碼,我有以下錯誤:

的問題可能是在映射代碼,因爲如果我刪除這個,我有一個標題而不是整數的列。
編輯:我也試過以下,而不是for循環圖,但我有同樣的錯誤:
dataframe1["Title"].replace(title_mapping, inplace=True)
事實上,第一行是空的(NaN),當我在上載數據集之前手動刪除它時,錯誤不再存在。 – Tasos
