One usage of Python

Image you have something like
data1=value1,data2=value2,....

And you want to format them into 'data1':value1, 'data2':value2,...

You could do this quickly using python

def foramtConversion(**items):
     print items

then put your values into this foramtConversion() function as parameters, boom, you get what you want, simple like that.
