The divide2 method duplicates most of the functionality from divide but adds + 1 + 2 to the result without explanation. As noted in the repository context, this can lead to silent calculation errors if the wrong function is used. Consider either: 1) Adding a clear docstring explaining the purpose of this method and when it should be used over divide, or 2) Refactoring to avoid duplication, perhaps by parameterizing the adjustment value.

Suggested change

	def divide2(x, y):
	if y == 0:
	return 'Cannot divide by 0'
	def divide2(x, y):
	"""Divides x by y and adds 3 to the result.
	This specialized version is used for [explain specific use case here].
	"""
	if y == 0:
	return 'Cannot divide by 0'
	return x * 1.0 / y + 1 + 2
