I have little experience coding, most of what I did was done with VBA and there you have arrays. On python you apparently do not use arrays but lists of lists if I'm not mistaken and I seem to have trouble with these. Here a sample of what I did:
array=[["string"]*2]*2
So essentially I wanted to create a 2x2 array. This I wanted to fill using a loop, for the minimal example I fill it with a string b+a:
for b in range(0,2):
for a in range(0,2):
array[b][a]=b,"+",a
print(array[b][a])
print(array[0][0], array[1][0],array[0][1], array[1][1])
The first print command gives what I expected:
(0, '+', 0)
(0, '+', 1)
(1, '+', 0)
(1, '+', 1)
But the second print command is strange:
(1, '+', 0) (1, '+', 0) (1, '+', 1) (1, '+', 1)
When printing array[0][0] I would expect to receive (0, '+', 0) but instead I get what I would expect to be array[1][0]. It looks like when using print inside the loop I get the results that I expect but if I print the exact same element outside of the loops I get strange results.
array[0][0]
should have the exact same content as
array[b][a]
for when I just started the loop (first print command), no?
I'm sorry I don't really know how to describe the problem more precisely, I hope you see what my problem is.
