It is an implementation detail and we will get rid of it. It only happens when you read the Python script from a file. If you import it as a module or run with runpy, the NUL character is an error. >> Some characters can be used to hide/overwrite other characters when >> source is >> listed in common terminals: >> >> * BS (``\b``, Backspace) moves the cursor back, so the character after it >> will overwrite the character before. >> * CR (``\r``, carriage return) moves the cursor to the start of line, >> subsequent characters overwrite the start of the line. >> * DEL (``\x7F``) commonly initiates escape codes which allow arbitrary >> control of the terminal. ESC (``\x1B``) starts many control sequences. ``1円A`` means the end of the text file on Windows. Some programs (for example "type") ignore the rest of the file. _______________________________________________ Python-Dev mailing list -- [email protected] To unsubscribe send an email to [email protected] https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/[email protected]/message/CBI7ME3YUAVVH5B6LSC745GJSVUIZJHO/ Code of Conduct: http://python.org/psf/codeofconduct/
