python - basic write to file code not working

Question

I write a basic file write code -

    f = open('workfile', 'r+')

    f.write('0123456789abcdef')

I run the file at cmd at the same folder where I put workfile.txt file but I get the error -

IOError: [Errno 2] No such file or directory: 'workfile'

I tried also to convert to exe file with py2exe and run the exe file but nothing...

what is the problem?

thanks!

====================

the full error massage when check on compiler-

    Traceback (most recent call last):                                                                                                                               
    File "/home/ubuntu/workspace/.c9/metadata/workspace/2.py", line 1, in     <module>                                                                                 
    f = open('workfile', 'r+')                                                                                                                                   
    IOError: [Errno 2] No such file or directory: 'workfile'

Do you have a file called workfile? No, it's called workfile.txt. — cdarke

With "r+" mode, the file must already exist. Obviously, "workfile" doesn't exist. — tdelaney

rename 'workfile' to 'workfile.txt':

f = open('workfile.txt', 'r+')
