如print.开启一个新的缩进需要使用:(冒号),代表下一级别的语句块,如条件,循环或者函数定义.缩进最好使用四个空格.而且要注意缩进要一致,使用空格就全都用空格, 使用Tab就都使用Tab,混用就可能得到缩进错误:IndentationError: unindent does not match any outer indentation level 最后,务必注意,Python程序是大小写敏...
Continuation lines should align wrapped elements either vertically using Python’s implicit line joining inside parentheses, brackets and braces, or using ahanging indent[7]. When using a hanging indent the following should be considered; there should be no arguments on the first line and further ...
IndentationError: unindent does not match any outer indentation level 3. Python注释 编写程序时,注释非常重要。它描述了相应代码的功能作用,以便别人看懂你的代码。甚至你可能会忘记一个月前你编写的程序的关键细节。因此,花时间以注释的形式解释关键代码很有必要。 在Python中,使用 #符号开始编写注释,它延伸到换...
很长的行可以通过在括号内换行来分成多行,最好加上反斜杠来区别续行。The right circle/square/curly bracket at the end of multiple lines can be written on a single line, aligned with the indent of the previous line, or aligned with the first character of the first line at the beginning of ...

决定开始Python之路了,利用业余时间,争取更深入学习Python。编程语言不是艺术,而是工作或者说是工具,所以整理并遵循一套编码规范是十分必要的。所以今天下午我根据PEP 8整理了一份,以后都照此编码了,还会持续更新。 PEP8 Python 编码规范 一 代码编排 1 缩进。4个空格的缩进(编辑器都可以完成此功能),不使用Tap,更...
For example, here’s how we can combine these functions to build another function that deletes enough leading spaces from each line to ensure that the least-indented line of the block becomes flush-left, while preserving the relative indentations of all the other lines: def unIndentBlock(s...

multiple spaces after keyword:关键字后的多个空格,多于格式要求空格,删去。 indentation is not a multiple of four:缩进不是4的倍数,修改空格为偶数,2/4等。 missing whitespace around operator:缺少操作符周围的空格 行注释格式: #前两个空格,#后一个空格。 函数def编写格式:(expected 2 blank lines, found...
