You can also program your script in such a way that it should accept various options.Command Line Argumentsis an advanced topic and should be studied a bit later once you have gone through rest of the Python concepts. Print Page Previous ...
Internally, Python uses the following rules to identify falsy objects: Constants that are defined to be false: None and False The zero of any numeric type: 0, 0.0, 0j, Decimal(0), Fraction(0, 1) Empty sequences and collections: '', (), [], {}, set(), range(0) The rest of ...
Special cases aren't special enough to break the rules. Although practicality beats purity. Errors should never pass silently. Unless explicitly silenced. In the face of ambiguity, refuse the temptation to guess. There should be one-- and preferably only one --obvious way to do it. Although ...
