Example: Simple Calculator by Using Functions # This function adds two numbers def add(x, y): return x + y # This function subtracts two numbers def subtract(x, y): return x - y # This function multiplies two numbers def multiply(x, y): return x * y # This function divides two ...
Creating a basic calculator program in Python is a great way to get familiar with the language and its logic. Here's how to make a Python calculator and the tools you'll need to do it.

Python 3.8 adds a few new ones that can help you during coding and debugging. The difference between is and == can be confusing. The latter checks for equal values, while is is True only when objects are the same. Python 3.8 will try to warn you about cases when you should use == ...

Coding this in Python looks quite neat when you take advantage of the complex data type: Python from cmath import pi, exp def discrete_fourier_transform(x, k): omega = 2 * pi * k / (N := len(x)) return sum(x[n] * exp(-1j * omega * n) for n in range(N)) This func...

, which offers interactive coding tutorials, says you can learn Python in as little as two months. But that assumes you can sit in front of a computer every day and practice from 8 a.m. to 5 p.m. If you have a day job, six months may be a more realistic timeline. That would re...
