root=Tk()

for s in news_full:
    texr2=Label(root,text=s,font=("sans-serif",32))
    texr2.pack()

root.geometry('545x800')

root.mainloop()

so expected output is (ex for first element of list]

You can use wraplength when creating a Label object to make the text wrap by itself.

This is given in screen units, so if your window is 545 pixel wide (as in your example), you could pass a wraplength value of 545 such that it wraps within your window.

To have your text aligned to the left as in your expected output, you could pass the argument justify=LEFT, and anchor=W.

Your line where you create a label would therefore look like:

texr2=Label(root, text=s, wraplength=545, anchor=W, justify=LEFT, font=("sans-serif",14))

Note that I changed the font size so all your text fits to the window size.

You also want to ensure everything fills properly by packing with the arguments fill=BOTH and expand=True:

texr2.pack(expand=True, fill=BOTH)

Certainly use TK's automatic wrapping if possible. But if not, you can do the following:

from textwrap import wrap

s = "Some very long string. Or short. It does not matter really. Blah, blah, blah!\nIt can be multilined too!"
print "\n".join(wrap(s, 25))

So this will wrap any text to 25 characters per line. A list of lines will be returned.
