AI代码解释 *Numbers(数字)*String(字符串)*List(列表)*Tuple(元组)*Dictionary(字典) 三、 Python数字(Number) Python数字类型用于存储数值数值类型是不允许改变的,这就意味着如果改变数字类型的值,将重新分配内存空间 代码语言:javascript 代码运行次数:0 运行 AI代码解释 var1=10var2=20 也可以使用del语句删除...
Return a casefolded copy of the string. Casefolded strings may be used for caseless matching. Casefolding is similar to lowercasing but more aggressive because it is intended to remove all case distinctions in a string. For example, the German lowercase letter'ß'is equivalent to"ss". Sinc...

python基础的随笔更多是偏向于我个人代码实现和讨论,所以对于知识点不会有一个比较输入的说明,知识点可能会在之后系列再做总结。如果后面总结知识点我大概率会手打,截图属实起不到加强记忆的效果,如果可以我会尽量做一个知识点目录(同参考课程进度) 概述
