sorted method to sort by reading the key-value pair in the for Loop. Examples are as Follows:>>> for key in sorted (list (d.keys ())): ... print (key, ' = = ', d[key]) ... a = 1b + 2This section introduces a dictionary of one of Python's built-in types, a dictionary as an unordered collection of data stored in the form of Key-value pairs, fast searching, support for arbitrary nesting, growth and shortening as needed, and very flexible, so it is widely used in
