nalsb

The 10 programs from the Numerical Methods for Scientific Computing lab manual, packaged as a Python library. Ask for a program's source code with one line.

pip install nalsb

import nalsb as na

print(na.ques(4))        # program 4 (Newton-Raphson) + the lab-manual example
print(na.ans(4))         # program 4 + 2 worked examples with outputs

print(na.ques("gauss"))  # names work too: all lower case, no spaces
print(na.ans("jacobi"))

na.run("simpson")        # execute a program straight away
na.programs()            # list numbers and names

If you prefer no quotes, import the names:

from nalsb import *
import nalsb as na
print(na.ques(gauss))
print(na.ans(jacobi))

Programs

Common alternative spellings ("newtonraphson", "rungekutta", "simpsons", "lsq", ...) are accepted as well, and so are "Gauss" or "Runge-Kutta" (case, spaces and punctuation are ignored).
