Tuples in Python. In this tutorial we will learn about Tuples in python. We will learn how to define a tuple, add elements to it, delete elements and slicing function for tuples in python.
In this example, we callos.stat()to obtain the file attributes, including the size, which is accessed using thest_sizeattribute of the returned named tuple. By using these approaches, you can easily retrieve the size of a file in Python. Remember to handle exceptions, such asFileNotFoundErro...
Most of Python’s immutable built-in objects are hashable; mutable containers (such as lists or dictionaries) are not; immutable containers (such as tuples and frozensets) are only hashable if their elements are hashable. Objects which are instances of user-defined classes are hashable by defaul...

If input is of type FloatTensor or DoubleTensor, value should be a real number, otherwise it should be an integer. Parameters input (Tensor)– the input tensor. value (Number)– maximal value of each element in the output out (Tensor, optional)– the output tensor. ...

If the values cannot be evenly distributed among into groups, then the last group will either be returned as is, thrown out or padded with the value specified in fill_value. Parameters n (int)– The size of resulting groups lst –The list, tuple or string to group underfull_action (str...
Input value of unique_together must be a set of tuples. """ option_name = "unique_together" def __init__(self, name, unique_together): unique_together = normalize_together(unique_together) self.unique_together = {tuple(cons) for cons in unique_together} super().__init__(name) def...
You can also pass a list of strings or 2-tuples. The latter is used for passing queries and parameters in the same way ascursor.execute(). These three operations are equivalent: migrations.RunSQL("INSERT INTO musician (name) VALUES ('Reinhardt');")migrations.RunSQL([("INSERT INTO musicia...
