python read file operation

Question

I am trying to read numbers from a file in python. The file contains ONLY numbers. ALl numbers are decimal!! As asked, this is the file contents: 25 4 2 6 7

I get this error:

Traceback (most recent call last):
    File "readfile.py", line 18, in <module>
    a.append(int(data[i]))
ValueError: invalid literal for int() with base 10: 'f'"

This is my code:

check=0
while(check!=1):
    file=raw_input("Plase state the file name:")
    print "\n"
    try:
            check=1
            fo=open(file,"r",1)
    except IOError:
            print "NO such file or directory"
            check=0

data=0
a=[]
i=0
for line in file:
    data=line.split()
    print data
    a.append(int(data[i]))
    i=i+1
print a

fo.close()

Answer 1

How about spliiting the content and looping thru it.

with open('some_file','r') as fo:
    content = fo.read().split(" ")

for num in content:
    print num

Answer 2

You are doing...

for line in file:

You should be doing...

for line in fo:

Looping the file name string won't help you.

Also, you need to fix the iterator, i, on the data list. Or instead of fixing the iterator, you could do list comprehension:

a += [int(x) for x in data]
