(dict makes it easier to create dictionary instances, and list does the same for lists); Python also has a number of “meta” functions that operate on the language or its elements directly. The eval function, for example, takes a string containing Python and executes that code. Similarl...
>>>string=str("hello")>>>type(string)<class'str'> 字符串的特性与常用方法 特性:按照从左到右的顺序定义字符集合,下标从0开始顺序访问,有序 补充: 字符串的单引号和双引号都无法取消特殊字符的含义,如果想让引号内所有字符均取消特殊意义,在引号前面加r,如site = r’jike\tfm’, unicode字符串与r连用...

Acommentis a part of the code which is not executed by python. So we can leave some text in our code to make our code more readable. Python does not run the comment part. A comment in python starts with hash(#) symbol. This is how you write a comment in python ...
