python - 在python中导出excel或csv文件时删除第一列

Question

比方说，我将我的文件导出到 excel 中

声明出口

ln[] = writer = pd.ExcelWriter("df2018.xlsx")
writer = pd.ExcelWriter("df2018.xlsx", index = false)
df2018.to_excel(writer)
writer.save()

out[] = 
row0  (blank)  kanwil     jan 2018  feb 2018   janfeb 2018 
row1    0      sunarto    45878     545458     5454878
row2    1      hartanto   123456    545454     4444549
row3    2      pemabuk    9547      787896     4579798

（如果数据框是 df2018）

我的预期：

row0  kanwil     jan 2018  feb 2018   janfeb 2018 
row1  sunarto    45878     545458     5454878
row2  hartanto   123456    545454     4444549
row3  pemabuk    9547      787896     4579798

我想删除第一列

我试过了

pd.ExcelWriter("df2018.xlsx", index = false)

但它不起作用

如果我在导出 csv 或 excel 时要删除第一列该怎么办

事实上，我从下面的数据框（df2018）中获取信息：

<class 'pandas.core.frame.DataFrame'>
Int64Index: 154 entries, 2 to 155
Data columns (total 5 columns):
Kanwil                 149 non-null object
Cabang                 137 non-null object
Income Januari 2018    151 non-null object
Income Febuari 2018    151 non-null object
Income Jan-Feb 2018    151 non-null object
dtypes: object(5)
memory usage: 4.2+ KB
None

Answer 1

我相信您需要index=False在以下指定参数DataFrame.to_excel：

pd.ExcelWriter("df2018.xlsx")
df.to_excel(writer, index = False)
