python case convention code example

Example 1: python naming conventions

#module names should be all lowercase
import mymodule
#normal variables are lowercase_with_underscores
my_variable = 'value'
#constants are UPPERCASE
CONSTANT = 'never changes'
#classes are UpperCaseCamelCase
class MyClass(self):
    pass

Example 2: switch statements python

# Here is one way to implement a switch construct
# Switcher is a dictionary data type here
def week(i):
    switcher={
        0:'Sunday',
        1:'Monday',
        2:'Tuesday',
        3:'Wednesday',
        4:'Thursday',
        5:'Friday',
        6:'Saturday'
    }
    return switcher.get(i,"Invalid day of week")

print(week(5)) # Call the function

Example 3: pep8

# pep8 Style Guide for Lists
my_list = [
    1, 2, 3,
    4, 5, 6,
    ]
result = some_function_that_takes_arguments(
    'a', 'b', 'c',
    'd', 'e', 'f',
    )

Example 4: class name convention python

# PEP 8 Class names
# Class names should normally use the CapWords convention.

class MyClass:
  def __init__(self):
    # Variable and method names are snake_case
    self.load_time = 25
  def print_value(self, value):
    print(value)
