Selecting multiple columns in a pandas dataframe

Question

I have data in different columns but I don\'t know how to extract it to save it in another variable.

index  a   b   c
1      2   3   4
2      3   4   5
         


        

Answer 1

One different and easy approach : iterating rows

using iterows

 df1= pd.DataFrame() #creating an empty dataframe
 for index,i in df.iterrows():
    df1.loc[index,'A']=df.loc[index,'A']
    df1.loc[index,'B']=df.loc[index,'B']
    df1.head()
