oop - basic trouble opening a file with python object oriented programming script -

i'm new oop , having trouble writing , executing basic script open , read file.

i'm getting error ioerror: [errno 2] no such file or directory: '--profile-dir' when run this. what's wrong , how should fix it?

class testing(object):      def __init__(self, filename):         self.filename = filename         self.words = self.file_to_text()      def file_to_text(self):         open(filename, "r") file_opened:             text = file_opened.read()             words = text.split()             return words  alice = testing("alice.txt").file_to_text() print alice 

also, if i'd able make executable command line, these tweaks should make work, right?

import sys ... alice = testing(sys.argv[1]).file_to_text() print alice  line input in command line run it-----> ./testing.py alice.txt 

thanks in advance guys.

somewhere have filename = '--profile-dir' defined, being used in with open(filename, "r"), use with open(self.filename, "r") use actual attribute have defined in class:

filename = "foob" class testing(object):       def __init__(self, filename):         self.filename = filename         self.words = self.file_to_text()     def file_to_text(self):         print(filename)         open(filename, "r") file_opened:             text = file_opened.read()             words = text.split()             return words  

output:

foob ioerror: [errno 2] no such file or directory: 'foob' 

your code work fine using sys.argv once make change:

import sys  class testing(object):     def __init__(self, filename):         self.filename = filename         self.words = self.file_to_text()     def file_to_text(self):         open(self.filename, "r") file_opened:             text = file_opened.read()             words = text.split()             return words alice = testing(sys.argv[1]).file_to_text() print alice  :~$ python main.py input.txt ['testing'] 

if want use ./ put #!/usr/bin/env python @ top , chmod +x make executable.

you can avoid calling read , splitting using itertools.chain:

from itertools import chain class testing(object):     def __init__(self, filename):         self.filename = filename         self.words = self.file_to_text()     def file_to_text(self):         open(self.filename, "r") file_opened:             return list(chain.from_iterable(line.split() line in file_opened))
