我正在尝试在数据帧Current_tape中使用重新索引功能为变量'New Account'重新索引。但是,在使用重新索引功能后,我看到naan(无值)
Current_tape2 = Current_tape.reindex(columns=['New Account'])
Current_tape2['New Account'] = Current_tape2['New Account'].astype(str)
输出
New Account
0 NaN nan
1 NaN nan
2 NaN nan
3 NaN nan
4 NaN nan
Current_tape2 = Current_tape.reindex(columns=['New Account'])
Current_tape2['New Account2'] = Current_tape2['New Account'].astype(str)
expected result
New Account
0 r1
1 r2
2 r3
3 r4
4 r5
