我有一个包含一列的数据框,我想把它分成两列,一列标题为' fips'和另一列'row'

我的数据框df看起来像这样:

          row
0    00000 UNITED STATES
1    01000 ALABAMA
2    01001 Autauga County, AL
3    01003 Baldwin County, AL
4    01005 Barbour County, AL

我不知道如何使用df.row.str[:]来实现分割行单元格的目标.我可以df['fips'] = hello用来添加一个新列并填充它hello.有任何想法吗？

         fips       row
0    00000 UNITED STATES
1    01000 ALABAMA 
2    01001 Autauga County, AL
3    01003 Baldwin County, AL
4    01005 Barbour County, AL

我有一个熊猫数据帧(这只是一小块)
