Can anyone please help me in understanding the following python code

Code :
-
def mergeSort(alist):
print("Splitting ",alist)
if len(alist)>1:
mid = len(alist)//2
lefthalf = alist[:mid]
righthalf = alist[mid:]

mergeSort(lefthalf)
mergeSort(righthalf)

Re: Can anyone please help me in understanding the following python code

2013-05-30 Thread bhk755 
Thanks for the reply Chris.

I am newbie to python, so please excuse me if I am asking chilly questions.

Can you please explain more about the following sentence.
"When it says "Splitting" with a single-element list, it then 
immediately prints "Merging" and returns (because all the rest of the 
code is guarded by the 'if'). Execution then continues where it left 
off, in the parent."

Because I am not sure how the control can go back to top of the function unless 
 there is no loops there.

Also, Can you please let me know how did you found out that I am using Python 2 
Interpreter.

Thanks Chris, Wolfgang and Joshua for your replies.

In step 2b, all the steps from 1 through 3 are executed again (twice). 
Soon, those calls will just output "Splitting" followed by "Merging"; 
and then we go back to 2c. That's why it *seems* that the code goes 
from 3 to 2c. You'll notice that the call depth decreases when this 
happens

Chris, Can you please let me know what makes the control of the program code go 
to  2c after the output "Merging". 

Also, please look into the following output, 



 before calling main mergesort

 after calling main mergesort

[17, 20, 26, 31, 44, 54, 55, 77, 93]

-

In the above output, the control goes to "HERE AFTER SPLIT" after the "Merging" 
statement which is of-course the last statement in the function.On what 
condition this is happening.
Ideally as per my understanding, after the last statement of a function the 
control should come out of the function. 
Please correct me if I am wrong here.
There is something with respect-to functions in python that I am not able to 
understand.

Got It!!!,  Finally.  Thanks Dave

So, the control goes back to the place after the recursive function is called 
once the no. of element is equal to one and starts merging after which it will 
again start to split the remaining items.

Thank you Chris for your multiple explanations. It was also very useful.

One final question, Is there a way to edit the message once it has been posted?

2013-04-08 Thread bhk755 
I am trying to create 2D arrays without using advanced features like numpy, for 
this I have created 2 separate modules arrays.py and array2D.py. Here's the 
code for that:

arrays.py module:

def __init__( self, size ):

self._size = size

PyArrayType = ctypes.c_int * size
self._elements = PyArrayType()
print "type is e", type(self._elements)
#self._elements = ctypes.c_int * size

print "Elements are self.element %s" % self._elements
# Initialize each element.
#for i in range(self._size):
#   self.clear( i )


# Returns the size of the array.
def __len__( self ):
return self._size

# Gets the contents of the index element.
def __getitem__( self, index ):
assert index >= 0 and index < len(self), "Array subscript out of range"
return self._elements[ index ]

# Puts the value in the array element at index position.
def __setitem__( self, index, value ):
assert index >= 0 and index < len(self), "Array subscript out of range"

self._elements[ index ] = value

# Clears the array by setting each element to the given value.
def clear( self, value ):
