I have a .csv file that has data like that:

index, name,    id
1      john     512
2      Anne     895
3      Angel    897
4      Lusia    777
So I want to filter them by name endings and get names only which have vowel endings. And the result must be like that:

    index, name,     id
    1      Anne     895
    2      Lusia    777
After filtering, I want to save the result in another .csv file. I am trying various ways to get the correct result, However, I could not do that. please help me :(

What I have tried:

pandas.read_csv and pandas.DataFrame.to_csv to read and write csv files. For selection you can use something like df[df.name.str[-1].apply(lambda x: x in ['a', 'e', 'i', 'o', 'u'])]

Did you try something like below.

Filtering:

Python

df[df.name.str[-1].apply(lambda x: x in ['a', 'e', 'i', 'o', 'u'])]

Refer: Lambda and filter in Python Examples[^]

Saving to CSV:

Python

df.to_csv('new-location\\output_filtered_sample1.csv', index=False, quoting=1)

Refer: pandas.DataFrame.to_csv — pandas 1.5.0 documentation[^]

Overall:

Python

df = pandas.read_csv('location-of-file\\sample1.csv')
filtereddf = df[df.name.str[-1].apply(lambda x: x in ['a', 'e', 'i', 'o', 'u'])]
filtereddf.to_csv('new-location\\output_filtered_sample1.csv', index=False, quoting=1)

try out!
