As per Stack Overflow, Python is one among the fastest growing programming languages in the world. Forbes says that Python saw the 7th largest demand increase in past years. Due to this, there will be an acute shortage of skilled and certified Python professionals. The job opportunities for Python have also increased tremendously. According to indeed.com, the average annual salary of a Python developer in the US is $123,000.
Python is one of the most popular programming languages of the 21st century. It is a general-purpose language and has been around for over 20 years. One of the biggest reason why Python is becoming so popular is that Python has an elegant and simple English like syntax which makes it fairly easy to learn. With it’s gentle and gradual learning curve, Python is considered as the best introductory languages programming language.
Here we have the list of topics if you want to jump right into a specific one:
Python is a general-purpose language, which means that it can be used to write software applications in a variety of domains without being restricted to a particular domain. This feature sets Python apart from domain-specific languages. Being a general-purpose language, Python can do a number of interesting things. Some of them are listed below:
Since the release of the new version of Python, that is Python 3, there has been a bit of a debate in the coding community about which python version is better. Whether python 3 is better than python 2 or not is a rather subjective question and the selection between the two eventually comes down to the personal preference but one must know how Python 2 and Python 3 are different. Python 3 is a fundamentally different version from Python 2.
Let’s see all the key differences between Python 2 and Python 3
|Basis of the difference||Python 2||Python 3|
|In Python 2, we treat print as a statement rather than a function and hence there is no need to put the text inside parentheses.||In Python 3, we explicitly treat print as a function, which means the text you want to print has to be inside the parentheses or you will get a syntax error.|
|Integer division||In Python 2, the interpreter treats the numbers that we type without any decimal points as integer which might lead to unexpected outcomes of certain mathematical operations. e.g., 5/2 in Python 2 will give the result as 2 instead of 2.5. To get the result as 2.5, we will have to write 5.0/2.0||In Python 3, the interpreter automatically identifies what should be the data type on the basis of the type of value. So the result of 5/2 in Python 3 is by default calculated as 2.5 which is way more convenient than Python 2.|
|Input||In Python 2, we use raw_input() function to take inputs from users. This function only returns the string representing the user’s input which we have to convert into the desired datatype.||In Python 3, input() method is used to take the input from the user. The type of input is also automatically interpreted in Python 3.|
|String Type||The implicit string type in Python 2 is ASCII||The implicit string type in Python 3 is Unicode|
While learning as a beginner programmer, you should follow these tips which will help you to deal with the new concepts:
It is important to have consistency while learning any new programming language. It is important that you should make a commitment to write code every day. As it will play with your muscle memory which is a very important part in programming. Increase you level of coding gradually but never stop playing around with the basic coding part. You may end up learning something new even about te basics.
This will also help you to keep a good grasp of basics such as:
Print the type of the element:
Use docstring to add multi line descriptive descriptions in your code:
Performs operations and play around with them:
The list does not end here, there are plenty other basic things that you can practice.
Whether you are new Python data structures (dictionaries, lists, strings etc.), or you are debugging an application, the best learning tools is an interactive Python shell.
To use the interactive Python shell, first you should install Python on your computer. The step-by-step installation procedure of python you can learn in this tutorial. To activate and use the interactive Python shell, simply open the terminal on your system and run python or python3 depending on your version of installation. Now that you know shell is open, you can write code.
Hitting a bug is normal when you start writing a complex program. Don’t get frustrated, it happens with everyone! Instead, grip these moments as a pride and think of yourself as a bug bounty hunter. Debugging your own code will help you learn even more.
It is important to have a methodological approach while debugging the code, which will help you to find where your code is breaking down. Going through your code step by step in its executable order and make sure each part of code works is a great way you want it to do.
Always try to build a small project for each concept. This will help you build confident of writing Python program, as well as this will help you to develop the muscle memory. Once you have a solid foundation on basic data structures (dictionaries, strings, sets, lists), object-oriented programming, and writing classes. This will also teach you the most of your programming concepts. For the best of career growth, check out Python training course to get certified. Also, Intellipaat is providing a free Python interview questions and answers, which will help to excel your career.
