Python

Important changes from Java

• When you pass an object to a function, and "reassign" it using its local function argument name, the outside objects won't get reassigned. This is because Python reassigns the local name only. This is a important difference from Java.

Useful techniques

• To iterate over two lists at the same time, use the zip built-in function:

for a,b in zip(list1, list2):

Casts

• To cast a float to an integer, you can use the built-in int() function.

Exceptions

• Sample code to deal with an exception:

	try:
	    doSomething()
	except Exception, inst:
	    print str(inst.args)
	    print str(sys.exc_info()[0])

This will give you information about the raised exception type.
