[ACCEPTED]-Pandas delete parts of string after specified character inside a dataframe-pandas
Accepted answer
You can reformat the values by passing a 2 reformatting function into the apply method as 1 follows:
from StringIO import StringIO
import pandas as pd
data = """ obs a b c d
1 1-23-12 1 2 3
2 12-23-13 4 5 5
3 21-23-14 4 5 5"""
# Build dataframe from data
df = pd.read_table(StringIO(data), sep=' ')
# Reformat values for column a using an unnamed lambda function
df['a'] = df['a'].apply(lambda x: x.split('-')[0])
This gives you your desired result:
obs a b c d
0 1 1 1 2 3
1 2 12 4 5 5
2 3 21 4 5 5
