I'm working on a Python problem where I need to set up a tuple with a pre-defined length n (being n an input of the program), where each element must have a specific float value (e.g. H), similar to what is possible to do with NumPy arrays in this way:
import numpy as np
arr = H*np.ones(n)
Is it possible for a tuple?
You can create one with a generator expression:
tuple(H for _ in range(n))
Instead of a constant value H you can fill the tuple with an arbitrary expression depending on the iteration variable (which was not used above and therefore named _ by convention):
tuple(f(i) for i in range(n))
For example, to fill the first half with G and the second half with H, you can use a conditional expression as f(i):
tuple(G if i < n/2 else H for i in range(n))
