Split string by count of characters

Question

I can\'t figure out how to do this with string methods:

In my file I have something like 1.012345e0070.123414e-004-0.1234567891.21423... which means there is no deli

Answer 1

I always thought, since string addition operation is possible by a simple logic, may be division should be like this. When divided by a number, it should split by that length. So may be this is what you are looking for.

class MyString:
    def __init__(self, string):
        self.string = string
    def __div__(self, div):
        l = []
        for i in range(0, len(self.string), div):
            l.append(self.string[i:i+div])
        return l

>>> m = MyString(s)
>>> m/3
['abc', 'bdb', 'fbf', 'bfb']


>>> m = MyString('abcd')
>>> m/3
['abc', 'd']

If you don't want to create an entirely new class, simply use this function that re-wraps the core of the above code,

>>> def string_divide(string, div):
       l = []
       for i in range(0, len(string), div):
           l.append(string[i:i+div])
       return l

>>> string_divide('abcdefghijklmnopqrstuvwxyz', 15)
['abcdefghijklmno', 'pqrstuvwxyz']

from itertools import izip_longest

def grouper(n, iterable, padvalue=None):
    return izip_longest(*[iter(iterable)]*n, fillvalue=padvalue)
