byte array in python w3schools

A significant difference between strings and bytes is that the latter only allows for ASCII characters in its literals. # Python 3 key = bytes ( [0x13, 0x00, 0x00, 0x00, 0x08, 0x00]) # Python 2 key = ''.join (chr (x) for x in [0x13, 0x00, 0x00, 0x00, 0x08, 0x00]) I find it more convenient to use the base64 module. Youll have no way to access the interior of a numeric value. This doesnt mean that you should. You just have the option of creating a new object of the same type but with a different value, which you can do through a new assignment. Otherwise, youll have immutable derived objects. Remember that tuples can store mutable objects, in which case the underlying tuple wont be hashable. Its important to point out that if you use mutable objects as the value of an immutable class like the above, then you wont be able to prevent mutations on that value: In this example, you cant reassign .value to hold the number 42 because your class is immutable in that sense. Strings are quite useful in Python programming. You can access the values of these attributes through the instance using dot notation. Like tuples, lists are sequences of arbitrary objects. independent. compatible with that passed in via this argument. Similarly, john.__dict__ holds instance attributes and their values for the current instance, john. The recommended way to store and load data: dtype=[('time', [('min', '
