一.Python 数字(Number) 整数、浮点数和复数都属于Python数字的范畴。在Python中,它们被定义为 int、float 和 complex类。 我们可以使用type()函数来判断一个变量或值属于哪个类。同样地,isinstance(检查对象,特定的类) 函数用于检查对象是否属于特定的类。 整数可以是任意长度,但受可用内存的限制。 浮点数最多可提...

在cpython 实现的 python 虚拟机当中,下面就是 cpython 内部列表实现的源代码: typedef struct { PyObject_VAR_HEAD /* Vector of pointers to list elements. list[0] is ob_item[0], etc. */ PyObject **ob_item; /* ob_item contains space for 'allocated' elements. The number ...
那么有个特殊情况,假设我们删除的下标不存在,或者说要移除的元素不存在,是会报错:ValueError: list.remove(x): x not in list;IndexError: pop index out of range 其他常用方法 我们根据场景来看一些方法 1、假设我们要判断一个 list 内某元素存不存在,或者说 list 内某元素的个数,用什么方法?
