In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
The if clause body starts on line 3 since it is indented an additional level, and ends on line 4 since line 5 is indented a level less, a.k.a. outdented. The colon (:) at the end of a control statement line is Python syntax; not an aspect of the off-side rule. The rule can be realized without such colon syntax.
Fortran 90 removed the need for the indentation rule and added line comments, using the ! character as the comment delimiter. COBOL. In fixed format code, line indentation is significant. Columns 1–6 and columns from 73 onwards are ignored. If a * or / is in column 7, then that line is a comment.
As seen on page C‑2 of the newspaper. This code generates "page C‑2" just like the plain code "page C-2", but prevents a line break at the hyphen. However, like , the use of ‑ instead of "-" renders the source text harder to read and edit. Don't use it unless it is really necessary to avoid a line break.
In Python, functions are first-class objects that can be created and passed around dynamically. Python's limited support for anonymous functions is the lambda construct. An example is the anonymous function which squares its input, called with the argument of 5:
For example, Python's PEP 8 is a widely recognized style guide that outlines best practices for writing Python code. In contrast, languages like C or Java may have industry standards that are either formally documented or adhered to by convention.
A newline (frequently called line ending, end of line (EOL), next line (NEL) or line break) is a control character or sequence of control characters in character encoding specifications such as ASCII, EBCDIC, Unicode, etc. This character, or a sequence of characters, is used to signify the end of a line of text and the start of a new one.

IronPython allows running Python 2.7 programs (and an alpha, released in 2021, is also available for "Python 3.4, although features and behaviors from later versions may be included" [170]) on the .NET Common Language Runtime. [171] Jython compiles Python 2.7 to Java bytecode, allowing the use of the Java libraries from a Python program. [172]
