What is a dictionary comprehension in Python?

Python Dictionary Comprehension. Mathematically speaking, a dictionary (dict) is a mapping for which the keys have unique values. In that sense, a dict is a function (since one key only has one value). It is quite easy to define the function f(x) = y2 and make a dict comprehension in Python using these lines of code:
