I am trying to take the linspace of between 2 columns of a dataset. Heres an example.

    a   b   C   D

0   3   13  3   13

1   4   14  4   14

2   5   15  5   15

I am trying to take the linspace between columns a and b a and turn it into a new column. Here is what I have so far:

def takinglinspace(): 

    i = 0

    for i in range(0,len(test.index)): 

        new=np.linspace(test['C'].iloc[i],test['D'].iloc[i],5)



test['E']= test['E'].apply(takinglinspace())

If i run the takinglinspace() function by itself it works. I get 3 lists of linspace values between the 2 columns. I cant seem to figure out how to insert that into the new column.

Applying the test['E'].apply I get the error

KeyError                                  Traceback (most recent call last)

Any reply is appreciated. Thanks.
