I’m trying to loop on numbers between 44100000 to 44999999 in python.
I tried this:

f=open('of','w')
i=44100000
while i<=44999999 :
     f.write(str(i)+"\n")
     i+=1

but it is incomplete! the tail of the of file is:

notice the last number that

when I did it again the same code gave me this tail of file:

and the third run made complete & correct out put:

while this worked correctly every time:

for i in range(44100000,44999999):
     f.write('%d\n' % (i,))

What is the problem?
Thanks

You fail to close the file before terminating the process. It is good practice to use resources that need cleaning up in a with statement:

with open('of', 'w') as f:
    f.write("Stuff")

# f.close() will be called automatically upon leaving the with-scope
