[Tutor] how to calculate execution time and complexity

[Praveen Singh]

>>> splitWord('google', 2)
    ['go', 'og', 'le']
    >>> splitWord('google', 3)
    ['goo', 'gle']
    >>> splitWord('apple', 1)
    ['a', 'p', 'p', 'l', 'e']
    >>> splitWord('apple', 4)
    ['appl', 'e']


def splitWord(word, number):
	length=len(word)
    	list1=[]
    	x=0
    	increment=number		
    	while number<=length+increment:
        	list1.append(word[x:number])
      		x=x+increment
        	number=number+increment

    	for d in list1:
        	if d=='':
            		list1.remove('')
    	return list1

I am getting the desired output and this code is working fine..but i
think it is quite bulky for this small operation.

qus.1-- can you guys suggest me some better solution??
qus 2-- i know writing just a piece of code is not going to help me. i
have to write efficient code.i want to know how to calculate execution
time of my code and
        can you guys suggest me some links so that i can learn how to
find complexity of code??

Thanks in advance...
