Python is one of the most widely used programming languages. It’s getting a lot of popularity these days because of so many Python frameworks in IoT, Machine Learning, Deep Learning, and Artificial Intelligent space.
These Python Tutorials will help you in getting mastery over the Python Programming. The tips and tricks shared by us will enable you to write pythonic code with high performance, reusability, readability, and maintainability.
“Sort a dictionary by value” can mean returning a list of pairs or building a new mapping, depending on what the next step needs. Pass a dictionary straight to sorted() and Python orders its keys, then returns those keys in…
The seaborn palette API changed in 0.13.x. The old form triggers a FutureWarning. Pass the same column to both x and hue to use the new palette parameter. When you need a violin plot Violin plots earn their place when…
len() on a list of ten million integers takes roughly 2.5 microseconds, while a Python loop over the same list takes roughly 300 milliseconds. The difference comes from a stored count rather than a faster algorithm, which decides the length…
The Collatz conjecture resists proof despite its simple rule. Take any positive integer. If it is even, divide it by 2. If it is odd, multiply it by 3 and add 1. Repeat this process and the conjecture says you…
Every character your computer stores has a number behind it. The letter A is 65, the letter a is 97. Once you know that, turning a into 1 and A into 27 is a single subtraction. What you need Method…
You have probably typed git checkout feature-branch a hundred times without thinking about it. Then one day you tried to restore a deleted file and found git checkout handles that too. Single command doing two completely different jobs. That confusion…
Python’s range() hands back a range object instead of a list of numbers, and that single choice explains the stop value that causes off-by-one loops. The object stores three integers and works out each element when something asks for it,…
Python never shipped a switch statement, so generations of us built our own out of long if-elif chains and dict lookups. I ran every style on Python 3.11.16 this morning, side by side, and the surprise was not speed. You…
Debug prints all repeat the same chore, because the variable name gets typed once as a label and once as the value. The f-string shorthand prints both from a single expression, so the label can never drift out of sync…
Every list of strings eventually needs to become one string, and the line that does it reads backwards. The separator calls the method while the list supplies the items, so a comma-joined row comes out as a one-liner once you…
