Python PEP 8 Naming: snake_case for Variables and Functions
PEP 8 prescribes snake_case for functions, methods, variables, and module names. PascalCase (CapWords) is used for classes. CONSTANT_CASE is used for module-level constants.
user_count = 5 # snake_case variable
def calculate_total(): # snake_case function
class OrderProcessor: # PascalCase class
MAX_RETRY_COUNT = 3 # CONSTANT_CASE
