>>> type(a) <type 'int'> Python是一门动态类型语言,和C、JAVA等语言不同,你无需手动指明变量的数据类型,根据赋值的不同你可以随意更改一个变量的数据类型,举例来说刚才我们把“整数”这个数据类型赋值给了a这个变量,现在我们再次赋值一个内容为test的"字符串"(String)数据类型给变量a,然后用type()函数来确...

The None object is a value you often assign to signify that you have no real value for a variable, as in: try: x except NameError: x = None Then it’s easy to test whether a variable is bound to None: if x is None: some_fallback_operation( ) else: some_operation(x)...
In Python, assert is a simple statement with the following syntax:Python assert expression[, assertion_message] Here, expression can be any valid Python expression or object, which is then tested for truthiness. If expression is false, then the statement throws an AssertionError. The assertion_...
