Breaking long number literal into multiple lines

Breaking long string literals into multiple lines is not problem, e. g.

long_string = ("This is a very very long string literal for writing it as one-line "
               "literal. More appropriate is using more lines so that the code" 
               "will be more readable.")

But what about long integer literals, e. g. 

long_number = 12312323456782556897455666645555554787825401568014564565678978201245667185

Is there some similar possibility?

You can do:

long_numer = int("1231232345678255689745"
                 "5666645555554787825401"
                 "5680145645656789782012"
                 "45667185")

As long as this is not in your hot codepath, the extra step should not cause issues.

In python, there is no max value for an integer. If you really want to do something like this, you can try

x = '12312323456782556897455666645555554787825401568014564565678978201245667185' \
    + '12312323456782556897455666645555554787825401568014564565678978201245667185'

Now, to fetch the value, you can simply do

long_number = int(x)

Except for Pep8, you are not really achieving much by doing this though.

Another way you can parse the value could be using ast

import ast

long_number = ast.literal_eval(x)
