使用 Pandas 刪除 DataFrame 的幾行后，標(biāo)題不會(huì)改變；它保持行被刪除之前的狀態(tài)。我怎樣才能得到更新的標(biāo)題？for row in range(rowStart): # rowStart is my index (int). It means it should drop all rows up to this    df.drop(row, inplace=True)df = df.reset_index(drop=True)header = list(df) # even assigning the header after the drop, it keeps returning the same as beforeprint(header)print('')print(df) # the DataFrame is ok, without the removed rows (as expected)最小的例子：data = {    '': '',    'asd': '',    'bfdgfd': '',    'trytr': '',    'jlhj': '',    'Job': 'Revenue',    'abc123': 1000.00,    'hey098': 2000.00}df = pd.DataFrame(data.items(),    columns=['Unnamed: 0', 'Unnamed: 1'])header = list(df)print(header)print('')print(df)startRow = 5for row in range(startRow):    df.drop(row, inplace=True)df = df.reset_index(drop=True)header = list(df)print(header)print('')print(df)
