slayeroffrog :
I have a a Dataframe loaded from a .csv that looks like this
name code
accounting
a 1
c 3
HR
b 2
I need to change so it reads like this
name code dept
a 1 accounting
c 3 accounting
b 2 HR
What can I do to achieve this?
Datanovice :
IIUC,
we can use .loc
to assign to a new column, ffill
and .dropna()
to get your target df.
df.loc[df['code'].isnull(),'dept'] = df['name']
df['dept'] = df['dept'].ffill()
df_new = df.dropna(subset=['code'])
print(df_new)
name code dept
1 a 1.0 accounting
2 c 3.0 accounting
4 b 2.0 HR
