Description

-
I have confirmed this bug exists on the latest version of pandas.
-
(optional) I have confirmed this bug exists on the master branch of pandas.
I'm trying to remove certain characters in a DataFrame, in this case, I am trying to remove the ñ.
Code Sample
df = pd.DataFrame([['añoos','asññ','ÑolÑÑss'],['añoos','asññ','ÑolÑÑss']], dtype='string')
df.replace({'ñ':'n',
'Ñ':'N'},
regex = True, inplace = True)The output is:
| 0 | 1 | 2 | |
|---|---|---|---|
| 0 | añoos | asññ | ÑolÑÑss |
| 1 | añoos | asññ | ÑolÑÑss |
Problem description
If I do not specify the dtype to string, the output is the expected as follows:
Expected Output
df = pd.DataFrame([['añoos','asññ','ÑolÑÑss'],['añoos','asññ','ÑolÑÑss']])
df.replace({'ñ':'n',
'Ñ':'N'},
regex = True, inplace = True)
print(df)| 0 | 1 | 2 | |
|---|---|---|---|
| 0 | anoos | asnn | NolNNss |
| 1 | anoos | asnn | NolNNss |
Output of pd.show_versions()
