python list insert first
You'll have to pass the new ordinal position to insert using len in this case: In [62]: a=[1,2,3,4] a.insert(len(a),5) a Out[62]: [1, 2, 3, 4, 5].,Let's say that the second list is called array . You can use array.insert(0, "xyz") or array = ["xyz"] + array to add "xyz" to the beginning of the second list.
