foo=long_function_name(var_one,var_two,var_three,var_four) 当if语句的条件部分足够长,需要跨多行编写时,值得注意的是,两个字符的关键字(即 if),加上一个空格,再加上一个开括号,会为多行条件的后续行创建一个自然的4个空格缩进。这可能会在if语句内嵌的缩进代码块的可视上产生冲突,后者也会自然地缩进...
In [26]: %matplotlib inline图2-6 Jupyter行内matplotlib作图 2.3 Python语法基础 在本节中,我将概述基本的Python概念和语言机制。在下一章,我将详细介绍Python的数据结构、函数和其它内建工具。 语言的语义 Python的语言设计强调的是可读性、简洁和清晰。有些人称Python为“可执行的伪代码”。
