read in from file

Hi all,

trying to write a program that will read a file in like:

python myprog < inputFile

the program needs to store each line a an entry in a list.

Expand|Select|Wrap|Line Numbers

  
li = []
 
for i in range(0,9): #<- these must be the correct range.    

    temp = raw_input("")

    li.append(temp)

This code works but you have to hard code how many lines there will be (see comment). I need my program to terminate at the EOF. I have looked around for a couple hours but havent had enormous luck finding anything.

Tryed entering in

Expand|Select|Wrap|Line Numbers

  
if(temp==\0):

      break

and similar but not having to much luck. Thanks for reading!

Iteration on a file object will terminate when the EOF character is reached.

Expand|Select|Wrap|Line Numbers

 f = open('file.txt')

for i, line in enumerate(f):

    print 'Line number %d' % i

    ## do more stuff
 
f.close()

Thanks bvdet .

For anyone with a similar problem as me this is the way I ended up doing it:

Expand|Select|Wrap|Line Numbers

  
def readWords():

    while 1:

        line = raw_input()

        if line != "":

            listOfWords.append(line);

        else:

            break

#End read words method

Ooops. The previous code does not detect EOF (well it does sometimes, just not not always...)

Regardless, this code works:

Expand|Select|Wrap|Line Numbers

  
# reads words from the input file

def readWords():

    jake = sys.stdin

    listOfWords= jake.readlines()

    listOfWords = [i[:-1] for i in listOfWords]

    return listOfWords
