Hello, @anantharamakrishnan !
There are two things on your code that I'd like to talk about:

1 -

``````else:
print "Enter a valid destin.."
return False``````

In this case, I can't say you're wrong, you're actually informing the user that he/she did wrong but returning a logical value due that, where you don't do any sort of "error handling", it will be wrong. When you return that value, you'll try to calculate it and things will go wrong.

Try to consider things will be all great and the user won't try to cause errors so you can pass the assignment and after that, you can come up with all sorts of error handling!

2 -

``elif city == "los Angeles":``

This could be a problem when the input is "los angeles". Even by using the .lower() function, if you inform "Los Angeles",it won't be equal to "los Angeles" due to that uppercase "A" at "Angeles".
But that would happen if someone informs Los Angeles!

Other than that, you're doing a really good job!
Keep up the good work!
