首先,Python会将源代码文本组织为逻辑行(Logical Lines),逻辑行尾会被Python加上NEWLINE标记。我们知道,文本文件采用回车(Mac)、换行(Unix/Linux),或回车换行(DOS/Windows)作为行结束的标志,在Python中,这样形成的行叫作物理行(Physical Lines)。一般情况下,一个物理行即是一个逻辑行,但是通过显式或隐式的行连接...
#This is a long comment #and it extends #to multiple lines 另一种方法是使用三重单引号 '''或者三重双引号 """。 三重引号通常用于多行字符串。但它们也可以用作多行注释。除非它们是文档字符串(docstring),否则它们不会生成任何额外的效果。 """This is also a perfect example of multi-line commen...
You are given a sequence of statements without indentation. Find the number of ways in which the statements can be indented to form a valid Python program. Input The first line contains a single integerN(1 ≤ N ≤ 5000) — the number of commands in the program.Nlines of the p...

Python is very particular about program layout, especially with regard to lines and indentation, so you’ll want to pay attention to this information if you are coming to Python from another language. Lines and Indentation A Python program is composed of a sequence of logical lines, each made...
②依次选择 File - Settings - Editor - Inspections,在 Python下找到 PEP8 coding style violation 选项,在右下角的 Ignore errors 里点击加号可以添加需要忽略的警告信息ID(ID信息见后面附录),例如想要忽略indentationcontainsmixed spaces andtabs这个警告,只需要添加其ID:E101 即可 ...
# and split into a list of lines: lines = docstring.expandtabs().splitlines() # Determine minimum indentation (first line doesn't count): indent = sys.maxsize for line in lines[1:]: stripped = line.lstrip() if stripped: indent = min(indent, len(line) - len(stripped)) ...
Indentation is not only for aesthetic purposes, but also for readability. Each indent level should have 4 spaces. The elements packed by consecutive lines should either be arranged implicitly in Python, that is, vertically aligned with parentheses, square brackets and curly brackets, or be indented...

Explanation: Here, the backslash (\) allows breaking a long statement into multiple lines and maintains a correct syntax. 5. Whitespace Rules in Python Python ignores the extra spaces except in the case of spacing during indentation, which leads to errors. Some of the most important Whitespace ...
