Question

***我在Pandas上遇到错误，请帮忙

df.reset_index(drop=True)
ind = list(df[df['BasePay'] == 0.0].index)
df.drop(df.index[ind])

错误输出为-

---------------------------------------------------------------------------

      1 df.reset_index(drop=True)
      2 ind = list(df[df['BasePay'] == 0.0].index)
----> 3 df.drop(df.index[ind])

如果我正确理解，您正在尝试删除“ BasePay”列为0.0的行。您可以简单地使用boolean indexing进行此操作，以保持所需的行像这样：

newDF = df[df['BasePay'] != 0.0]

IndexError：索引超出范围（熊猫）
