Hello everyone, the standard structure of a python-program which is taught in all of the books I on python I read by now is simply something like:
#!/usr/bin/python print "Hello, world!" ^D While reading about structuring a larger code-base, unit-testing, etc I stumbled on the idiom #!/usr/bin/python def main(): print "Hello, world" if __name__ == "__main__": main() ^D While experimenting with this I found that the second version in most cases is *a lot* faster than the simple approach. (I tried this both on Linux and Windows) I found this even in cases where the code con- sists simply of something like j=0 for i in xrange(1000000): j+=i print j How come the main()-idiom is not "the standard way" of writing a python-program (like e.g. in C)? And in addition: Can someone please explain why the first version is so much slower? Regards, Manuel -- A hundred men did the rational thing. The sum of those rational choices was called panic.
