Problem on filtering data on csv using python

Question

index,    name,     id,  status
1,        John,     500, online
2,        Anne,     485, offline

try to avoid using apply(). Instead use a string method. (Assuming the ‘numbers out of order’ that you are referring to are the index numbers. To remedy that, use reset_index)

df = pd.read_csv('data.csv', skipinitialspace=True)
df = df.drop('index',axis=1)
df[df['name'].str.endswith(('a','e','i','o','u'))].reset_index(drop=True).to_csv('output.csv', index_label='index')

output.csv now has:

index,name,id,status
0,Anne,485,offline
1,Lusia,777,offline
