Why python has limit for count of file handles?

Question

I writed simple code for test, how much files may be open in python script:

for i in xrange(2000):
    fp = open(\'files/file_%d\' % i, \'w\')
    fp.write(s         


        

Answer 1

The number of open files is limited by the operating system. On linux you can type

ulimit -n

to see what the limit is. If you are root, you can type

ulimit -n 2048

now your program will run ok (as root) since you have lifted the limit to 2048 open files
