Title
Body
I have a following DataFrame : from pandas import * df = DataFrame({'foo':['a','b','c'], 'bar':[1, 2, 3]}) It looks like this: bar foo 0 1 a 1 2 b 2 3 c Now I want to have something like: bar 0 1 is a 1 2 is b 2 3 is c How can I achieve this? I tried the following: df['foo'] = '%s is %s' % (df['bar'], df['foo']) but it gives me a wrong result: >>>print df.ix[0] bar a foo 0 a 1 b 2 c Name: bar is 0 1 1 2 2 Name: 0 Sorry for a dumb question, but this one pandas: combine two columns in a DataFrame wasn't helpful for me.
