read file into array separated by paragraph Python

I know this question was asked long before but just putting my inputs so that it will be useful to somebody else at some point of time. I got to know much easier way to split the input file into paragraphs based on the Paragraph Separator(it can be a \n or a blank space or anything else) and the code snippet for your question is given below :

with open("input.txt", "r") as input:
    input_ = input.read().split("\n\n")   #\n\n denotes there is a blank line in between paragraphs.

And after executing this command, if you try to print input_[0] it will show the first paragraph, input_[1] will show the second paragraph and so on. So it is putting all the paragraphs present in the input file into an List with each List element contains a paragraph from the input file.

import itertools as it


def paragraphs(fileobj, separator='\n'):
    """Iterate a fileobject by paragraph"""
    ## Makes no assumptions about the encoding used in the file
    lines = []
    for line in fileobj:
        if line == separator and lines:
            yield ''.join(lines)
            lines = []
        else:
            lines.append(line)
    yield ''.join(lines)

paragraph_lists = [[], [], []]
with open('/Users/robdev/Desktop/test.txt') as f:
    paras = paragraphs(f)
    for para, group in it.izip(paras, it.cycle(paragraph_lists)):
        group.append(para)

print paragraph_lists

This is the basic code I would try:

f = open('data.txt', 'r')

data = f.read()
array1 = []
array2 = []
array3 = []
splat = data.split("\n\n")
for number, paragraph in enumerate(splat, 1):
    if number % 3 == 1:
        array1 += [paragraph]
    elif number % 3 == 2:
        array2 += [paragraph]
    elif number % 3 == 0:
        array3 += [paragraph]

This should be enough to get you started. If the paragraphs in the file are split by two new lines then "\n\n" should do the trick for splitting them.
