Errno 2 No Such File or Directory on 2 splits

I have this code

import urllib.request
fw = open("myfile.txt", "r")
red = fw.read()
line = red.split("\n")
blue = line.split("@")[0]
i=0
while i<len(blue):
    try:
        try code is here
        try:
            try code is here
        except:
            print(blue[i] + " is " + "having e1")
    except:
        print(blue[i] + " is " + "having e2")

    i+=1

I am getting

Errno 2 No Such File or Directory

when I try to run my file. However, when I remove the line blue = line.split("@") it works fine.

What I want to do is to repeat this code on all the lines of myfile.txt - so I split \n first to get one line of the file then I want to get the characters before @ in this line and put it in the string blue

I can't understand why it work when I remove blue = line.split("@")

Any help would be appreciated.

line = red.split("\n") 
blue = line.split("@")[0]

When you do red.split("\n"), you obtain a list of lines. So line in your code is essentially a list of lines.

To demonstrate:

>>> red = '''\                                             
... This is line 1                                          
... This is line 2                                         
... This is line 3'''                                       
>>> red.split('\n')                                         
['This is line 1', 'This is line 2', 'This is line 3']

You cannot perform split on a list. Instead, get each item of line and perform split on it.

Here is a list-comprehension way of dealing with the issue:

blue = [x.split('@')[0] for x in line]

In above code, we iterate through each item in line (which is a list of lines as already explained). In each iteration, x takes each value out of line. x takes one line, does split on that, then on next iteration, takes next line from list, splits and continues till end.
