Naming convention

Python has certain objects naming convention

In general, it is better to adhere to this convention. However, if a particular library or module uses different convention, it is worth following the style used in them.

Not all rules are described in this section. More information can be found in PEP8 in English or Russian.

Variable names

Variable names should not overlap with operators and names of modules or other reserved values. Variable names are usually written entirely in large or small letters. It is better to stick to one of option within a script/module/package.

If variables are constants for module, it is better to use names written in capital letters:

DB_NAME = 'dhcp_snooping.db'

For ordinary variables it is better to use lower case names:

db_name = 'dhcp_snooping.db'
testing = True

Module and package names

Names of modules and packages are given in small letters.

Modules can use underscores to make names more understandable. For packages it is better to select short names.

Function names

Function names are given in small letters with underscores between words.

def ignore_command(command, ignore):

    ignore_command = False

    for word in ignore:
        if word in command:
            return True
    return ignore_command

Class names

Class names are given with capital letters, no spaces.

class CiscoSwitch:

    def __init__(self, name, vendor='cisco', model='3750'): = name
        self.vendor = vendor
        self.model = model
