Naming variables

PEP 8: Function and Variable Names

Function names should be lowercase, with words separated by underscores as necessary to improve readability.

 

Variable names follow the same convention as function names.

Reserved keywords

and	as	assert	break	continue
class	def	del	elif	else
except	False	finally	for	from
global	if	import	in	is
lambda	None	not	or 	nonlocal
pass	raise	return	True	try
while	with	yield

Not reserved, but don’t use it

int str list set ...

# And all type names, 
# function names, module names etc.
