Python: Dictionary with multiple values per key Leave a Comment / dictionary, Python / By Varun

In this article, we will discuss how to create and manage a dictionary in which keys can have multiple values.In python, if we want a dictionary in which one key has multiple values, then we need to associate an object with each key as value. This value object should be capable of having various values inside it. We can either use a tuple or a list as a value in the dictionary to associate multiple values with a key.Let’s understand it by some examples,

Create a dictionary with a list as the value # Create a dictionary where multiple values are # associated with a key word_freq = {'is': [1, 3, 4, 8, 10], 'at': [3, 10, 15, 7, 9], 'test': [5, 3, 7, 8, 1], 'this': [2, 3, 5, 6, 11], 'why': [10, 3, 9, 8, 12]}

In this dictionary, keys are strings, and with each key string, we have a list of numbers associated as a value field. So, basically, in this dictionary, multiple values are associated with a key.

Python could be effortlessly read and understood by even the amateur developers, this is because of its simplicity in syntax and this one of the main reasons for the popularity of python. As python is an interpreted language, one can also rapidly experiment it by changing the code base of the python. This capability of python makes it even more popular among all types of developers.

Experienced and supportive python community

More than 30 years before, the python was created; actually it is a lot of time for any programming language community to grow and mature. And it adequately supports the developers ranging from the starters to the expert levels. Python for beginners course is also offered by the community of python with the experts to guide. There is an infinite amount of documentation, video tutorials and guides are available for python language. Learners or developers from any age or skill level can make use of it and receive the support as per their requirement to knowledge enhancement particularly on the python programming language.

Hundreds of python libraries and frameworks

Python has extraordinary libraries, due to its sponsorship of corporate and supportive huge community of python. In the initial period of development, you can use it to select and save your own time and effort. You can also be extremely benefitted by using lots of cloud media services which offer cross-platform support tools like a library. For natural language processing or scikit-learn, nltk-like libraries with a specific focus are also available for machine learning applications. There are multiple frameworks and libraries available for python like matplotlib for plotting graphs and charts, Django for server-side web development, etc.

Versatility, reliability, speed and efficiency

Enquire any developer of python; they would completely agree that the python language is more reliable, efficient and faster than the most other modern languages. Nearly in any kind of environment, it can be used and no one will face any kind of performance issue irrespective of the platform they work. Python can be used in a variety of environments like desktop applications, mobile applications, hardware programming, web development, etc. This is one additional best thing about the versatility of the language python and the high number of applications makes the versatility of python more attractive to use.

The flexibility of python

A python language is more flexible by which it provides the developer with a chance to try and explore something exclusive. If a person is an expert in python language then there is no limitation to build similar kinds of things but they can also experiment something different.

End line

This is some of the reason for the supersonic growth of the python. This language is being adopted by most of the budding developers throughout the world because of its incredible features. Python is being a top choice for the developers with its capabilities and ease of hiring.

Everything you need to know about python programming language

In the fast-growing world, python has become one of the most highly popular programming languages. Numerous reasons are available to learn the Python programming language. The main reason behind this is that language is easy to learn and simple to use. Python works on distinct platforms like Mac, Raspberry Pi, Linux, and Windows, and more. Python developers write the code in very fewer lines whereas the complexity level is lower in python languages. The python for beginners sets a great path to achieve their goal in corporate fields. Here comes some of the top reasons to learn the python language.
