30. Print numbers with 2 decimal places. Write a Python program to print the following numbers up to 2 decimal places. Click me to see the sample solution 31. Print numbers with sign (2 decimals). Write a Python program to print the following numbers up to 2 decimal places with a sign...
string.split(separator),把字符串按照 separator 分割成子字符串,并返回一个分割后子字符串组合的列表; string.strip(str),去掉首尾的 str 字符串; string.lstrip(str),只去掉开头的 str 字符串; string.rstrip(str),只去掉尾部的 str 字符串。 列表和元组 列表和元组,都是一个可以放置任意数据类型的有序集合。
以上代码中,[1,2,3] 是List 类型,“Runoob” 是String 类型,而变量a 是没有类型,她仅仅是一个对象的引用(一个指针),可以是 List 类型对象,也可以指向 String 类型对象。 3.可更改对象和不可更改对象 在python 中,strings,tuples, 和 numbers 是不可更改(重新赋值后,原值不再存在)的对象,而 list,dict等...
