Give us some specific questions and sure, we'll help. And in case this occurs to you to try it, a listing of your C++ code with "How do I convert this to Python?" is NOT a specific question.

this is my python code

----------------------------------

read = open('sample.txt', 'r')

a = read.readlines()

for line in a :

print line,

------------------------------------

the above code will print all the line in the file. but if i wan it to print only certain % of the line(for example: 50% of the line). how do i code it?

[jcl]

The syntax foo[m:n] will give you a slice of the list foo from indices m (inclusive) to n (exclusive). len(foo) will give you the length of the list foo. Sooo...

for e in foo[0:len(foo)/2]:
	print e

will print the first half the list. Careful if len(foo) is odd: integer division rounds down. Same trick works with strings.

now i got other problem.

t = len(a) * 0.6

t will definitly be a decimal. how can i change it to the whole number without the decimal, so that i can apply to n in foo[m:n].

n has to be integer

is this what you are looking for?

t = int(len(a) * 0.6)
