Python hex() function is used to convert any integer number ( in base 10) to the corresponding hexadecimal number. Notably, the given input should be in base 10. Python hex function is one of the built-in functions in Python3, which is used to convert an integer number into its corresponding hexadecimal form.
The hex() function converts the integer to the corresponding hexadecimal number in string form and returns it.
The input integer argument can be in any base such as binary, octal, etc. Python will take care of converting them to hexadecimal format.
number: It is an integer that will be converted into hexadecimal value.
This function converts the number into the hexadecimal form, and then it returns that hexadecimal number in a string format.
Please note that the return value always starts with ‘0x’ (without quotes), which proves that the number is in hexadecimal format.
# app.py print("Enter the number: ") # taking input from user num = int(input()) # converting the number into hexadecimal form h1 = hex(num) # Printing hexadecimal form print("The ", num, " in hexadecimal is: ", h1) # Converting float number to hexadecimal form print("\nEnter a float number") num2 = float(input()) # converting into hexadecimal form # for float we have to use float.hex() here h2 = float.hex(num2) # printing result print("The ", num2, " in hexadecimal is: ", h2)
In the above example, we used the Python input() function to take the input from the user.
See the output.
Enter the number: 541 The 541 in hexadecimal is: 0x21d Enter a float number 123.54 The 123.54 in hexadecimal is: 0x1.ee28f5c28f5c3p+6
See the following program.
# app.py print("Enter the number: ") # taking input from user num = int(input()) # converting the number into hexadecimal form h1 = hex(num) # Printing hexadecimal form # we have used string slicing here print("The ", num, " in hexadecimal is: ", h1[2:]) # Converting float number to hexadecimal form print("\nEnter a float number") num2 = float(input()) # converting into hexadecimal form h2 = float.hex(num2) # printing result print("The ", num2, " in hexadecimal is: ", h2[2:])
See the output.
Enter the number: 541 The 541 in hexadecimal is: 21d Enter a float number 123.65 The 123.65 in hexadecimal is: 1.ee9999999999ap+6
On the above program, we have used string slicing to print the result without ‘0x’.
We have started our index from position 2 to the last of the string, i.e., h1[2:]; this means the string will print characters from position 2 to the last of the string.
See the following program.
# app.py numberEL = 11.21 print(numberEL, 'in hex =', float.hex(numberEL)) numberK = 19.21 print(numberK, 'in hex =', float.hex(numberK))
See the output.
➜ pyt python3 app.py 11.21 in hex = 0x1.66b851eb851ecp+3 19.21 in hex = 0x1.335c28f5c28f6p+4 ➜ pyt
See the following code.
# app.py class AI: id = 0 def __index__(self): print('__index__() function called') return self.rank stockfish = AI() stockfish.rank = 2900 print(hex(stockfish))
In the above example, we have used the index() method so that we can use it with hex() function.
See the output.
➜ pyt python3 app.py __index__() function called 0xb54 ➜ pyt
Without the 0x prefix, you need to specify the base explicitly. Otherwise, it won’t work.
See the following code.
# app.py data = int("0xa", 16) print(data)
With the 0x prefix, Python can distinguish hex and decimal automatically.
You must specify 0 as the base to invoke this prefix-guessing behavior, omitting the second parameter means to assume base-10.)
If you want to convert the string to an int, pass the string to int along with a base you are converting from. Both strings will suffice for conversion in this way.
# app.py hexStrA = "0xffff" hexStrB = "ffff" print(int(hexStrA, 16)) print(int(hexStrB, 16))
See the output.
➜ pyt python3 app.py 65535 65535 ➜ pyt
In the all above examples, we have used Python int() method.

Alright - Python isn't simply one more programming language. It should have something, which is the reason the business giants use it. Furthermore, that too for different purposes. Developers at Google use Python to assemble framework organization systems, parallel information pusher, code audit, testing and QA, and substantially more. Netflix utilizes Python web development services for its recommendation algorithm and media player.
Massive community support
Python has a steadily developing community that offers enormous help. From amateurs to specialists, there's everybody. There are a lot of instructional exercises, documentation, and guides accessible for Python web development solutions.
Today, numerous universities start with Python, adding to the quantity of individuals in the community. Frequently, Python designers team up on various tasks and help each other with algorithmic, utilitarian, and application critical thinking.
Python is the greatest supporter of data science, Machine Learning, and Artificial Intelligence at any enterprise software development company. Its utilization cases in cutting edge applications are the most compelling motivation for its prosperity. Python is the second most well known tool after R for data analytics.
The simplicity of getting sorted out, overseeing, and visualizing information through unique libraries makes it ideal for data based applications. TensorFlow for neural networks and OpenCV for computer vision are two of Python's most well known use cases for Machine learning applications.
Thinking about the advances in programming and innovation, Python is a YES for an assorted scope of utilizations. Game development, web application development services, GUI advancement, ML and AI improvement, Enterprise and customer applications - every one of them uses Python to its full potential.
The disadvantages of Python web improvement arrangements are regularly disregarded by developers and organizations because of the advantages it gives. They focus on quality over speed and performance over blunders. That is the reason it's a good idea to utilize Python for building the applications of the future.

Python is one of the most popular programming languages currently. It looks like this trend is about to continue in 2021 and beyond. So, if you are a Python beginner, the best thing you can do is work on some real-time Python project ideas.
We, here at upGrad, believe in a practical approach as theoretical knowledge alone won’t be of help in a real-time work environment. In this article, we will be exploring some interesting Python project ideas which beginners can work on to put their Python knowledge to test. In this article, you will find 42 top python project ideas for beginners to get hands-on experience on Python
Moreover, project-based learning helps improve student knowledge. That’s why all of the upGrad courses cover case studies and assignments based on real-life problems. This technique is ideally for, but not limited to, beginners in programming skills.
But first, let’s address the more pertinent question that must be lurking in your mind:

Use pandas to upload CSV, TXT and Excel files
Learning Python isn’t the easiest thing to do. But consistency is really the key to arriving at a level that boosts your career.
We hear a lot about millennials wanting things to easy. In reality, there are a lot of young professionals who believe that they can do more for their companies but are being held back by the work cultures they are faced with at the onset of their careers.
Having been lucky enough to have found a job after my studies, I remember immediately feeling a wave of disappointment a very short while after starting my new job. I felt like a cog in a massive machine. I wasn’t really anything other than a ‘resource’. An extra 8–15 hours of daily man power depending on my boss’ whim.
The result, was the eventual disenchantment and lack of motivation simply because, for the most part, I was expected to be quiet and do my job in the hope of one day being senior enough to effect significant changes. And while the older generation would generally tell me to suck it up, I couldn’t see myself sucking it up for 5 years or more. I knew I’d get stale and afraid of change, much like those telling me to stay in my place.
For anyone in a similar situation,**_ do your best to improve on your skills _**and find an environment that works for you. That’s the whole purpose of these articles. To get you on your way to freedom.
For this demonstration, I’ll use data from this Kaggle competition. It’s a simple CSV file containing data on individuals in the Titanic and the different profiles i.e. (age, marital status etc.)
I want to import this file to python. I’ll show you how to do this alongside all the possible troubleshoots you may encounter.
