it_json are columns that contain lists, for each row in a dataframe I want to add the lists
in a fresh column called full
def list_columns(df):
df2=df.copy()
for index,row in df.iterrows():
# print(row)
l=[]
if row['it_json_1']:
l+=row['it_json_1']
if row['it_json_2']:
l+=row['it_json_2']
if row['it_json_3']:
l+=row['it_json_3']
if row['it_json_4']:
l+=row['it_json_4']
df2['full'][index]= l
return df2
but list_columns(df) is giving me key error
>Solution :
Try to save the values into a list then assign them to the new columns "full"
full.append(l)
then after the loop ends:
df2['full'] = full
