PEP, or Python Enhancement Proposal, refers to several documents that describe new features that are proposed for Python and document aspects of Python, such as design and style. These documents are released to the developer community.
PEP 8 (also called PEP8 or PEP-8) is a PEP document that provides guidelines and the best practices for writing Python code. Written in 2001 by Guido van Rossum, Barry Warsaw, and Nick Coghlan, the main focus of PEP 8 is to improve the readability and consistency of Python code.
A few of the key guidelines to be followed according to PEP 8 are:
Naming Conventions
and  and  and  and  and Choosing sensible names that will save you time and energy later. For example, avoiding and  and  and  and  and  and  and single-letter names like l and O is more efficient, as these can look similar to 1 and 0 which and  and  and  and  and  and may confuse.
and  and  2. and Naming Styles
Functions: Use the lowercase word(s) separated by underscores. Example: my_function()b. Variables: Use lowercase single letters or word(s) separated by underscores. Examples: x, my_variableClass: Use camel case for all class names with no space between words. Example: MyClassConstants: Use uppercase single letter or word(s) separated by underscores. Examples: CONSTANT, MY_CONSTANTPackages: Use the short lowercase word(s). Do not separate the words with underscores. Example: mypackage
and  and  3. Code Layout
and  and  and  and  a. Using blank lines:
and  and  and  and  Surround top-level functions and classes with two blank lines.
class MyClass1:
pass
class MyClass2:
pass
def top_level_function():
return 1
Surround method definitions inside classes with a single blank line.
class MyClass:
def method_one(self):
 return 1
def method_two(self):
 return 2
and  and  and  Use blank lines sparingly within the functions to show clear steps. This can be done at the and  and  and  and  and  and  programmer's discretion
and  and  and  and  b. Maximum Line Length:
and  and  and  and  and  and  and  PEP 8 suggests lines be limited to 79 characters in length to allow users to have multiple and  and  and  and  and  and  and  files open next to one another while avoiding line wrapping.
and  and  and  and c. Indentation:
and  and  and  and  and  and  The key indentation rules laid out in PEP 8 are the following:
and  and  and  and  and  and  Use 4 consecutive spaces to indicate indentation.
and  and  and  and  and  and  Prefer spaces over tabs.
and  and  and  and  d. Lining up the Closing Brace:
PEP 8 provides two options for the position of the closing brace:
Line up the closing brace with the first non-whitespace character of the previous line.
list = [
		1, 2, 3,
		4, 5, 6,
		7, 8, 9
		]
and Line up the closing brace with the first character of the line that starts the construct.
list = [
		1, 2, 3,
		4, 5, 6,
		7, 8, 9
]
and  and  and e. Comments:
and  and  and  and  and One should limit the line length of comments and docstrings to 72 characters. Make sure to and  and  and  and  and use complete sentences, starting with a capital letter. Do not forget to update comments if and  and  and  and  and  and you change your code.
