How to strip last three characters from a column in Pandas Dataframe

I have a Pandas dataframe like this:

         Country  Ranking
0     Greece[e]      100
1      China[e]      200
2     Singapore      300
3  Australia[e]      400
4        Zambia      500
5        France      600
6     Canada[e]      700

I like to remove any ‘[e]’ under ‘Country’ column of the DF, to have this:

      Country  Ranking
0     Greece      100
1      China      200
2  Singapore      300
3  Australia      400
4     Zambia      500
5     France      600
6     Canada      700

When I use:

df.Country = df.Country.str.strip('[e]')

I get the ‘[e]’ is removed including the last ‘e’ of country’s name (e.g. Singapore, Greece, France).

         Country  Ranking
0      Greec      100
1      China      200
2   Singapor      300
3  Australia      400
4     Zambia      500
5      Franc      600
6     Canada      700

Answer

.str.replace():

df["Country"] = df["Country"].str.replace(r"[e]$", "")
print(df)

Prints:

     Country  Ranking
0     Greece      100
1      China      200
2  Singapore      300
3  Australia      400
4     Zambia      500
5     France      600
6     Canada      700
