Pythonic Naming conventions

[psbasha]

Hi,

I would like to know what naming conventions we can follow for the following types of variables/sequences :

Variables :
-------------

Integer
Float
Boolean

Sequences :
--------------

Strings
List
Dictionary
Tuples

File

I understand that Python variables are "Dynamicall y Typed" ,that is one of the feature of it.But how the developer differentiate with different sequences or variables he is working with.

Thanks in advance

As I was reading your post, the words "Dynamicall y Typed" were running through my mind. I'm glad that you have that understanding. Because a function don't care about the type of it's arguments, I've settled on a nameType (sometimes long_nameType) naming "convention " for myself. But that mostly applies to instances of class objects. I don't differentiate between mutibles and non-mutibles the way that you have. As a rule, I use:
class: ThisClassName
def: ThisFuncName

useofThisClass = ThisClassName()
thisType = ThisFuncName()

Integer
Float
I just use descriptive names like
loopCount, distance, etc. Just wait 'til you meet Decimal and others that are not built in, but are very commonly used.

Boolean
conditionFlag

Strings
whateverStr

List
listofList

Dictionary
describeDict

Tuples
samehereTuple

File
alwaysFile

I hope that is useful to you. Thanks for posting. Keep it up.

Also, for short loops where the whole life of a counter can be seen in just a few line, i, j, k, do just fine. And for long life instance variablea shared by many methods, I use_very_descri ptive_names which may not need the Type at the end. This is all just personal style and I have seen "convention s" change over the years. If you look at the style that Tkinter was written in, you'll see what I think is a very common "pythonic" way of naming things. On the other hand, wxPython ToolKit uses C naming conventions because of the underlieing implementation and is the style that I prefer.

Take a look at this: http://www.python.org/doc/essays/styleguide/

Following are some guidelines I use:

single letter names for class instances ('a', 'b', 'c')
single letter name ('f') for an open file if contained in a small block of code
'i' (integer) when executing a range iteration
LineLineInterse ct3D, Plane3D - class definitions
clip_hole, add_weld, radius_cut, data_Defaults_p ath, import_data, trueAngleBetwee nMembers, formatDict, formatPtList - descriptive names for functions
PointRotate3D - descriptive names for functions with major functionality
pt_list or ptList - a list of points
bm_list or bmList - a list of beams
dd1, dd2, memDict, conn_dict - dictionaries

rot_arg - tuple (I mostly use lists)
ptWP, pt1, p1 - point objects
mem1 - the first selected member object

m, bm, col, mem, key - iteration on a list of:
material
beams
columns
members
dictionary keys

A descriptive name similar to lists - strings, integers, and floats
no_spa (number of spaces), left_dist (the distance from the left end)

I am still in 2.3 - not using sets yet

Thanks BV. I hadn't read that before. I am amazed how much of THE MAN's style I have picked up over the years just by reading library modules. My whitespace thinking exactly matches his. Great link (I bookmarked it).

Hi,

What naming conventions has to be followed for the Class Variables and Methods?.How to differentiate the Private ,Protected and Public Class Variables and Methods?Is there any conventions has to be followed.

Hi ,

I am not able to decide the Naming conventions for the following.

Variables :
--------------

Float
Integer
String
List
Dictionary
Tuples
File

Class Names

Private,Protect ed and Public
Class Variables

Class Methods

Functions

I have looked for various material in Internet .I am not able to get the consistency naming conventions.

Each one is following thier own naming conventions.

Thanks in advacne

It really comes down to a matter of personal style.
BV gave a great link. I gave suggestions. Please try to keep one post per topic so that all info ends up in one place. Thanks.

Hi ,

The naming conventions for UI in Python are similar to that of Application.

UI Variables and Methods

- Handlers
- Control Variables ( ID's,EDIT Box,Combo Box)
- Class Variables
- Call back names
- Event Handlers
- Other


Thanks in Advacne
