Returning value in a nested function when using memoization

closures dynamic-programming memoization nested-function python

I am trying to implement a count variable in the function below using dynamic programming specifically memoization. The method calculates the value in a Fibonacci sequence at a given index. I cannot figure out why the count (in this case the number of times this program executes) is not returned. Output: Addi…

How to write a function to fit data to a sum of N Gaussian-like peaks without explicitly defining the expression for every possible N?

curve-fitting lambda nested-function python scipy-optimize

I am trying to fit a progression of Gaussian peaks to a spectral lineshape. The progression is a summation of N evenly spaced Gaussian peaks. When coded as a function, the formula for N=1 looks like this: where A, e0, hf, S and fwhm are to be determined from the fit with some good initial guesses. Importantly…

Why aren’t python nested functions called closures?

closures nested-function python

I have seen and used nested functions in Python, and they match the definition of a closure. So why are they called “nested functions” instead of “closures”? Are nested functions not closures because they are not used by the external world? UPDATE: I was reading about closures and it g…
