Fix Python – Insert at first position of a list in Python [closed]

Question

Asked By – Fr0z3n7

How can I insert an element at the first index of a list?
If I use list.insert(0, elem), does elem modify the content of the first index?
Or do I have to create a new list with the first elem and then copy the old list inside this new one?

Now we will see solution for issue: Insert at first position of a list in Python [closed]

Answer

Use insert:

In [1]: ls = [1,2,3]

In [2]: ls.insert(0, "new")

In [3]: ls
Out[3]: ['new', 1, 2, 3]
