PyChecker
Verfasst: Montag 18. November 2002, 23:46
Mit PyChecker kann man die Syntax von Pythonscripts prüfen. Bei mir läuft das wunderbar mit SuSE Linux 8.1.
Hat jemand das Teil schon mal unter Windows getestet? Ich hätte da gern mal einen Erfahrungsbericht. PyChecker gibts bei http://pychecker.sourceforge.net/. Das Programm kann mit einer wahren Flut von Optionen gestartet werden. Damit kann man sich dann auch ne ganze Menge Ärger sparen.

Hat jemand das Teil schon mal unter Windows getestet? Ich hätte da gern mal einen Erfahrungsbericht. PyChecker gibts bei http://pychecker.sourceforge.net/. Das Programm kann mit einer wahren Flut von Optionen gestartet werden. Damit kann man sich dann auch ne ganze Menge Ärger sparen.
