Where goes wrong in this list manipulation?

Question

I am manipulating with the lists in Python.

In [52]: myList = [1,2,3,4,5]
In [54]: c=[[]]*10

In [55]: for i, elem1 in enumerate(myList):
   ....:     b = [e         


        

Answer 1

The source of your confusion is on this line

c=[[]]*10

Here you are creating a list of ten references to the same (initially empty) list. Thus as you append to the list in c[0] later on, you are also appending to every other list in c. Try

c = [ [] for _ in range(10) ]

This will create a new list 10 ten times, so you won't have the same referencing problem.

Answer 2

Lists in c are all the same object. You need to do at least:

c = [[] for i in xrange(10)]
