If you're taking math or science courses, you'll most likely only be allowed to use a handheld calculator on exams. When you're on your own, you're better off using something like Python.

Use a math library like NumPy or Numba, or compile your code to C with Cython. These external solutions do get the job done, and a whole subculture of Python revolves around using them well.

Using OpenAI’s Code Interpreter (now called Advance Data Analysis) provides more accurate calculations, in part because it writes a small Python program to perform the actual math.

And, all of NumPy’s operations take place outside the Python runtime, so they aren’t constrained by Python’s limitations. Using NumPy for array and matrix math in Python ...
