【问题描述】:
我有一个数据框,在删除第一行并在每次迭代中最后添加 DFM 值为 100% 的新行之后,我需要在这十行下方复制所有 10 行第 50 次。如下例所示。
df1:-
Cal Group DFM
1 period 1 39.36%
2 period 1 98.89
3 period 1 99.95%
4 period 1 99.97%
5 period 1 99.99%
6 period 1 100.00%
7 period 1 100.00%
8 period 1 100.00%
9 period 1 100.00%
10 period 1 100.00%
结果:- 我已打印 3 次并将值移动 3 次。但我需要一次又一次地这样做 50 次。
