    Python Reference (The Right Way) Returns the first operand that evaluates to False or the last one if all are True. or Unpacks the contents of a dictionary into the function call. @ (decorator) Returns a callable wrapped by another callable. (call operator) Return True if x is in the underlying dictionary’s keys, values or items (in the latter case, x should be a (key, value) tuple). Keys views are set-like since their entries are unique and hashable. If all values are hashable, so that (key, value) pairs are unique and hashable, then the items view is also set-like.

    The core built-in types for manipulating binary data are bytes and bytearray. They are supported by memoryview which uses the buffer protocol to access the memory of other binary objects without needing to make a copy. The array module supports efficient storage of basic data types like 32-bit integers and IEEE754 double-precision floating values. 11/26/2018В В· With these concepts in mind, let's review some of the available properties and methods of lists and dictionaries in Python. Although we do not intend to cover all of them, the following sections will give us a glimpse of what we can accomplish by using these data structures in this series.
