Set values for particular columns in a row of a Pandas Dataframe

Referring to Set value for particular cell in pandas DataFrame I see 

 df.set_value( rownum, colnum, 'Someval')

to set a given cell. Assume in my dataframe all the columns are integers.

Is there a way to use 

set_value

to set a range of columns in a given row, or do I need a different function? 

df.set_value ( rownum, colstart:colend, 'someval')

gave a syntax error.

After some contortion I found this:

df.ix[ rownum , colstart:colend] = 'Someval'

This one works but I was wondering about set_value or perhaps some other short way.

As noted directly above by @MaxU, you are looking for 

df.iloc[ rownum , colstart:colend] = 'Someval'
