Hi what is wrong with this code...I have written a small counter in python
for my website.I am keeping the numbe in a file.than whenever someone visit the page I open the count.txt file..add one to that num(after converting it into int) and than I print that number.
Again I open the file and than I want to write that incremented number in that file but it is giving errors.Where is the code wrong(I think it is in the conversion of int to str...)
Thanks in anticipation...

#!/usr/bin/python
import cgi

def main():
print "Content-type:text/html\n"

fh=open("count.txt")
data=fh.read()
fh.close()
data=int(data)+1

print "<html><body>Ok so this is counter:", data," </body></html>"
fh=open("count.txt")
str(data) # I am converting int data to string...
fh.write(data) # I am writing string into the count.txt file
fh.close()

main()

Hi,

When you open your file:

Quote:

fh=open("count.txt")

The syntax for this is, open(filename[,mode])

If mode is omitted, it will default to read-only. This will raise an exception if you try to write to it.

Try:

fh = open("count.txt","w+")

And remember for next time, it helps to post the error message
