My question is regarding saving values of variables in Python. More specifically I have two different scripts that calculate the same things with 2 different ways. What I want to do is to compare the values of the variables returned from the two scripts. So I was wondering if I can run the first script, save the values of one of my variables (let say a matrix V) and then run the second script and compare the values for the same variable as they are calculated by the second script.
Like @claymore said in the comments, this can be done with pickle. You store the variable you want from each into a pickle and then grab the pickle objects from the comparison script.
An example is below
script_a.py
# Save a dictionary into a pickle file.
import pickle
def funca():
favorite_color = { "lion": "yellow", "kitty": "red" }
with open("a.pickle","wb") as f:
pickle.dump( favorite_color, f)
funca()
script_b.py
# Save a dictionary into a pickle file.
import pickle
def funcb():
favorite_color = { "lion": "blue", "kitty": "orange" }
with open("b.pickle","wb") as f:
pickle.dump( favorite_color, f)
funcb()
compare.py
# Load the dictionary back from the pickle file.
import pickle
import os
os.system("python script_a.py")
os.system("python script_b.py")
a_fav = pickle.load(open( "a.pickle", "rb" ))
b_fav = pickle.load(open( "b.pickle", "rb" ))
print "script 1 had favorite = ", a_fav
print "script 2 had favorite = ", b_fav
