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()
