Hello There, We all know that line starting with "#" in Python is a comment.
We also know that when the first line of any file (with any extension) has "#!/usr/bin/env bash" and if you make it executable and do ./filename.ext in the terminal then it will be considered as bash file (in this case even if the extension is.py the terminal will take it as bash file.) This same thing also happens with Python (If the first line of the file has #!/usr/bin/env python then even if the extension is .txt, if you make it an executable then terminal will process it with python interpreter.) So far we know two things: 1. "#" makes the line a comment in Python. 2. If processing file with bash, no matter what the file extension is, if the first line of that file hsa "#!/usr/bin/env python" and it is an executable and you run it doing like ./filename.ext, the bash will call python interpreter to process that file. Now let's get back. I'm reading a book "A Byte of Python" (http://www.swaroopch.org/notes/Python). In this page: http://www.swaroopch.org/notes/Python_en:First_Steps, under the section Using a Source File. There is a line saying that "A word of caution on the shebang..". On the next line the book says we can use #!C:\Python32\python.exe to make it executable. My Question: Is it true that doing that is as same as doing #!/usr/bin/env python on Unix? Because I think that the matter of shebang is limited to Bash and Windows don't have a bash, it has a Command Prompt. And I don't think such thing happens in Windows. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
