Testing for EOF ?

[Pete Moscatt]

I am reasonably new to python and am trying to read several lines of text
from an open file.

Typically in other languages I used to use code like:

while not EOF()
read_text_in
...
How is this achieved with python ?

Regards
Pete

my_file = open('whatever.txt', 'r')
for line in my_file:
print line # Or whatever

Thanks Simon,

So the code should look like:

f=open(myfile,"r")

for some_var in f:
text=f.readline()
print text

Do I have this correct ?

Nearly - you don't need the text=f.readline() bit. A file object (as
returned to you by open()) is an iterator, and iterating over it gives
you the lines directly.

Why not give it a go? The nice thing about Python is how easy it is to
try stuff like this out at the interactive prompt. Err, *one* of the
nice things, that is. ;-)

BTW, newbies are more than welcome here, but there is a python-tutor
list[1] which might be more your speed if you are quite new to Python.
There are also a number of tutorials available[2] . I'd recommend
either the standard tutorial[3] or Dive Into Python[4] for someone
like you who already knows how to program but doesn't know Python.

Welcome to Python, and have fun.
