Consider the following DataFrame:

import pandas as pd
df = pd.DataFrame({'A':['aab','Aab','aaB']})
df
A
0 aab
1 Aab
2 aaB

To remove the trailing substring 'ab', use the Series' str.replace(~) method:

df['A'].str.replace('ab$', '', regex=True)
0 a
1 A
2 aaB
Name: A, dtype: object

Here, the $ is used to indicate the end of the string.
