Python example

Python has hidden shorthands to make your life significantly easier. To reverse a string, we simply add ::-1 as list indices

>>> a =  "ilovepython" 
>>> print a[::-1] 
nohtypevoli

The same trick can be applied to a list of integers as well. String manipulation is extremely easy in Python. For example, if you want to output a sentence using the following predefined variables str1 , str2 and lst3

>>> str1 = "Totally"
>>> str2 = "Awesome"
>>> lst3 = ["Omg", "You", "Are"]

Simply use the .join() method and arithmetic operators to create the desired sentence.

>>> print ' '.join(lst3)
Omg You Are
>>> print ' '.join(lst3)+' '+str1+' '+str2
Omg You Are Totally Awesome
