What is the difference between Dict and List comprehensions?
Python comprehensions, similar to decorators, are syntactic sugar structures that aid in the construction of modified and filtered lists, dictionaries, or sets from a given list, dictionary, or set. Using comprehensions saves a lot of time and code that might be much more verbose (with more lines of code). Let us look at a few situations when understanding may be quite beneficial.

List and dictionary comprehensions not only make code more compact and intelligible, but they also outperform standard for-loops in terms of speed. Dictionary comprehension refers to the process of transforming one dictionary into another. Items from the old vocabulary can be conditionally included in the new dictionary throughout this transformation, and each item can be modified as needed. Python Classes in satara When you wish to build a new list based on the values of an existing list, list comprehension provides a concise syntax. For example, suppose you wish to create a new list of fruits that only include the letter "a" in their names. The generator expression delivers only the generator object, whereas list comprehensions return the complete list. The values will be identical to those in the list, but they will be accessible one at a time through the next() method. List comprehensions are quicker than generator expressions because of this.
