If the result equals 0, then it can run interval-specific code. In this case, the function calls print() to add a newline, which starts a new row.These ( +=, -=, *= and /=) are called augmented arithmetic assignments. They correspond to the following methods: the i semantically means "in-place", which means that they modify the object (or reference in the case of numerics) without having to additionally assign them: foo += bar. is equivalent to: foo = foo + bar.Here is the logical equivalent code in Python. This function takes a Python object and optional parameters for slicing and returns the start, stop, step, and slice length for the requested slice. def py_slice_get_indices_ex(obj, start=None, stop=None, step=None): length = len(obj) if step is None: step = 1.

Well, to write greater than or equal to in Python, you need to use the >= comparison operator. It will return a Boolean value – either True or False.
