Question

I have a Python dataframe with about 1,500 rows and 15 columns. With one specific column I would like to remove the first 3 characters of each row. As a simple example here

Answer 1

Use vectorised str methods to slice each string entry

In [11]:
d['Report Number'] = d['Report Number'].str[3:]
d

Out[11]:
     Name Report Number
0  George       1234567
1    Bill       9876543
2   Sally       4434555
