Though perhaps not the case here, I‘ll just mention a problem that is 
worth being aware of when transferring a script from a Windows/DOS 
system to Unix. If the difference in line-ending conventions hasn‘t 
been taken care of (such as by using ASCII mode during FTP transfer), 
then the spurious ^M in the script‘s #! line can trip up the shell or 
the env command, since it will be trying to run the program python^M.
