Issue 9749: tuple-to-list conversion - Python tracker (original) (raw)

As I am new to Python and programming as a whole, I do not have extensive knowledge of how to correctly report a bug. And as such I must apologize for the inconvenience.

My lack of knowledge makes this only an assumption, but...

l [(1, 4, 7), (2, 5, 8), (3, 6, 9)] q = r = s = [] for i in range(len(l)): ... for x in l[i]: ... q.append(x) ... s = q ... q = [] ... print s, # print used to increase clarity ... r.append(s) ... print r # and the next is printed out as: ... [1, 4, 7] [1, 4, 7, [...]] [2, 5, 8] [1, 4, 7, [...], [2, 5, 8]] [3, 6, 9] [1, 4, 7, [...], [2, 5, 8], [3, 6, 9]] r [1, 4, 7, [...], [2, 5, 8], [3, 6, 9]] r[3] # for extra [1, 4, 7, [...], [2, 5, 8], [3, 6, 9]]

Supposed outcome for r being [[1, 4, 7], [2, 5, 8], [3, 6, 9]]
