using lamda to create anonymous function in python (one-line function)

	# định nghĩa 1 function không nhận đầu vào, luôn trả về True, gán nó cho biến ``f``
	In [1]: f = lambda: True
	# gọi hàm này và nó trả về giá trị True
	In [2]: f()
	Out[2]: True
	# định nghĩa 1 function trả về số lớn hớn số đã cho 1 đơn vị, gán function này cho biến f
	In [3]: f = lambda x: x + 1
	# hàm này cần 1 argument, câu gọi hàm dưới đây bị thiếu argument
	In [4]: f()
