how do I insert a column at a specific column index in pandas?

Can I insert a column at a specific column index in pandas? import pandas as pd df = pd.DataFrame({'l':['a','b','c','d'], 'v':[1,2,1,2]}) df['n'] = 0 This will put column n as the last column of df, but isn't there a way to tell df to put n at the beginning?
see docs: http://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.insert.html using loc = 0 will insert at the beginning df.insert(loc, column, value) df = pd.DataFrame({'B': [1, 2, 3], 'C': [4, 5, 6]}) df Out: B C 0 1 4 1 2 5 2 3 6 idx = 0 new_col = [7, 8, 9] # can be a list, a Series, an array or a scalar df.insert(loc=idx, column='A', value=new_col) df Out: A B C 0 7 1 4 1 8 2 5 2 9 3 6
