Swap columns in pandas dataframes

To replace the columns of the pandas DataFrame, use ix to specify the column names in the order after the replacement.

Example

df
'''
Suppose this is a dataframe df
    a   b   c   
A   0   1   2   
S   5   6   7   
'''

#When I run this code ...
df.ix[:,['a','c','b']]
'''
It will be as follows
    a   c   b   
A   0   2   1
S   5   7   6
'''

That's all for the points I stumbled upon as a pandas beginner.

Postscript: Of course, you can specify the column index numerically.
