Comparing the Go programming language vs Python, Go wins on raw speed, concurrency and single-file deployment, while Python wins on ease of learning, libraries, data science and AI. Pick Go for fast network services; pick Python for almost everything else. Go isn’t installed on my test machine, so the Go snippets appear as code only. … Read more >>
In Python, and is True only when both sides are true, or is True when at least one side is, and not flips a value. They’re spelled as plain English words, not && or ||: Every snippet below ran on Python 3.12.5; you can see the actual Windows Command Prompt output in each screenshot. I’ll … Read more >>
R vs Python comes down to focus. The R programming language was built by statisticians for statistics and charts, while Python is a general-purpose language that also happens to be excellent at data science. If you’re picking one, I’d start with Python. I’m not running R on this machine, so the R snippets are shown … Read more >>
Does not equal in Python is written as !=. It compares two values and returns True when they’re different and False when they’re the same: For this one I used Python 3.12.5 on a Windows laptop, and the screenshots show the scripts running in Command Prompt. I’ll cover how != treats numbers and strings, when … Read more >>
The quickest way to convert an integer to a string in Python is the built-in str() function: str(42) gives you ’42’. When the number goes inside a sentence, an f-string does the conversion for you: Nothing here needs a package; it’s plain Python 3.12.5, and I captured each run in a Windows Command Prompt. Below … Read more >>
Wondering what enumerate does in Python? It wraps any iterable and hands you each item together with its position, as an (index, item) pair. So in a for loop you get the counter for free: All the output below is copied from Python 3.12.5 on Windows, and the screenshots show the same runs in Command … Read more >>
Yes, you can put a class in a class in Python. Define the inner class inside the outer class body, and reach it as Outer.Inner. It’s called a nested or inner class, and it groups a helper type with its owner: Each example was saved as a .py file and run with Python 3.12.5; the … Read more >>
Running a Python script takes one command. Open a terminal in the folder that holds the file and type python followed by the file name.

So what does in mean in Python? It’s the membership operator: x in y asks whether x is inside y and gives back True or False. Its opposite, not in, returns the reverse: Screenshots here are real runs of Python 3.12.5 in the Windows Command Prompt, so the output is exactly what you’ll get. Below … Read more >>
A list of lists in Python is just a list whose items are other lists, which gives you rows and columns like a small spreadsheet. You create one with nested square brackets and reach a value with two indexes, row first: I ran the code below on Python 3.12.5 in a Windows Command Prompt, using … Read more >>
