How to make Dictionary Comprehension in Python? However, the performance gain may not be significant for small datasets. It also avoids the need to initialize an empty dictionary and append elements to it one by one. Dictionary comprehension combines it all in a single expression for faster execution. Is dictionary comprehension faster in Python? Yes, Dictionary Comprehension is faster because it is a highly optimized way to create dictionaries by taking use of a python interpreter more effectively. In dictionary comprehension, this very same dictionary is expressed or more precisely written in a concise syntax. The key is used to access or in a way trace the value associated with it. Similarly in a python dictionary, we have a key and its value I.e the key-value pair. Let us consider a real-life dictionary, if we had to look for a definition of any word, we would do so by looking for the word and then looking for the definition. ![]() To conceptualize dictionary comprehension we need to know how a dictionary works in python. It is a one-line expression that combines the functionality of loops, conditional statements, and dictionary initialization to generate a dictionary in a single line of code. Dictionary comprehension in Python is a concise way to create a dictionary from an iterable object. Much like list comprehension, dictionary comprehension is a method to make dictionaries easy. We will explore the concept of dictionary comprehension in Python and its syntax and its practical applications. These key-value pairs allow you to retrieve data with ease. Dictionaries are considered an integral part of python due to their efficiency in storing data. ![]()
