for example if you had a dataframe containing numbers from 1-10, and if it finds the value 5 while iterating, you want it to go back or forward a few rows to do perform some operation that has to be done row by row, in this case to keep it simple just skip the next row to resume the iteration, how can you do that?

```
import pandas as pd

df=pd.DataFrame([1,2,3,4,5,6,7,8,9,10])
df.columns=['number']

start=0
for index, row in df.iloc[start:].iterrows():
    print(index, row['number'])
    if row['number']==5:
        start=index+2

```

with this i just get:

```
0 1
1 2
2 3
3 4
4 5
5 6
6 7
7 8
8 9
9 10

```

but i wanted it to give me:

```
0 1
1 2
2 3
3 4
4 5
6 7
7 8
8 9
9 10

```
