一起学计算机英语与编程：Python大数据基础教程1

今天的内容如下所示：

Python is a very simple language, and has a very straightforward[ˌstreɪtˈfɔ:wəd]syntax(直截了当的语法). Itencouragesprogrammerstoprogram without boilerplate([ˈbɔɪləpleɪt],样板文件; 公式化，陈词滥调)code. The simplest directive in Python is the "print" directive - it simply prints out a line (and also includes a newline, unlike in C).

There are two major Python versions, Python 2 and Python 3. Python 2 and 3 are quite different. This tutorial uses Python 3, because it more semantically([sɪ'mæntɪklɪ],语义上地)correct and supports newer features.

For example, one difference between Python 2 and 3 is the statement. In Python 2, the "print" statement is not a function, and therefore it is invoked([ɪnˈvəʊk],调用)without parentheses([pəˈrenθəsi:z],小括号). However, in Python 3, it is a function, and must be invoked with parentheses.

有用句型：

to encourage sb to do sth : 鼓励某人做某事

计算机专业词汇：

directive：计算机编程指令

statement：计算机编程中的语句

function：计算机编程中的函数

搭配：

to invoke a function 调用函数

to call a function 调用函数

注：boilerplate注意发音，视频中发音错误，具体音标请参考上文
