Hello all
A question from very beginner.
I generate a simple example array and then print its elements on the screen.
f=[[0]*3]*3 # array initialization
for i in range(3):
for j in range(3):
f[i][j]=str(i)+str(j) # make simple example array
print f[i][j], # print resulting elements
print '\n'
00 01 02
10 11 12
20 21 22
So I generate element in loop and then print it and see all is ok.
But after that if I print the whole generated array, I see different
result with constant first number, as if "i" variable does not vary
and equals to "2". What is wrong?
>>> print f
[['20', '21', '22'], ['20', '21', '22'], ['20', '21', '22']]
I use python 2.7
