Convert plain numbers from file to list of integers

Question

I have a text file with some plain numbers that i want them as integers in a list.
For example i'd like this
299 314 427
to be converted to this
list = [[299], [314], [427]]
i read the text file
with open('C:/...', 'r') as f:
masses= f.read()
and then i use a for loop and spectra.split(' ') since a blank space is the only thing that separates the integers but it appeds to list every number separately

list = []   
masses.split(' ')  
for mass in masses:  
    list.append(mass)

the results is ['2','9','9',' ','3',......] how can i split them and append them in list ?

Answer 1

Using list comprehension:

>>> with open('FILEPATH') as f:
...     lst = [[int(n)] for n in f.read().split()]
... 
>>> lst
[[299], [314], [427]]

Without argument, str.split splits strings by consecutive whitespace (space, tab, newline, ..):

>>> 'a\t\tb\nc  d'.split()
['a', 'b', 'c', 'd']
>>> 'a\t\tb\nc  d'.split(' ')
['a\t\tb\nc', '', 'd']

Don't use list as a variable name. It shadows the builtin function list .
