我正在嘗試創(chuàng)建一個熊貓數(shù)據(jù)框，其中每一行都填充有相同的一組值，但是每行的起始列對于向下迭代數(shù)據(jù)框的每一行都增加1。這是我目前的方法，也是我希望獲得的數(shù)據(jù)框示例。我在這里做錯了什么？謝謝！import pandas as pdimport numpy as npdf_to_fill = pd.DataFrame(data=np.zeros((4,6)),columns=[1,2,3,4,5,6])values_to_fill = pd.Series(np.arange(1,4))# vars to iterate over dataframenum_rows = len(df_to_fill)# counter to keep track of how many columns to offset from to fill dataframe in loop belowcol_offset = 0for row in range(0,num_rows):    # Fill the first row from first column onwards, 2nd from 2nd column onwards,...    df_to_fill.iloc[row,col_offset:] = values_to_fill    # Fill the remaining columns in the row with the last value from the values to fill series    df_to_fill.iloc[row,:].fillna(values_to_fill.values[-1],inplace=True)        col_offset += 1offset_array = np.array([[1,2,3,3,3,3],[0,1,2,3,3,3],[0,0,1,2,3,3]])desired_df = pd.DataFrame(data=offset_array,columns=[1,2,3,4,5,6])
