To add an element to the end of a list, use list.append(element)

To add an element to the start of a list use list.insert(0, element)

To add all elements of a list to another list, use list.extend(other_list)

x = [1, 2, 3] x.append("a") print(x) # [1, 2, 3, 'a'] x.insert(0, "b") print(x) # ['b', 1, 2, 3, 'a'] x.extend(["x", "y", "z"]) print(x) # ['b', 1, 2, 3, 'a', 'x', 'y', 'z']

Thanks for your answer but i want to insert a text before every element of my list to have at final a text like:

x= [1, 2, 3]

y = t

the result be

t1, t2, t3

The resultant list would have to become a text list

x = [1, 2, 3] y = ["t" + str(i) for i in x] y ['t1', 't2', 't3']

Ah, OK.

x = [1, 2, 3] y = "t" for i, k in enumerate(x): x[i] = y + str(k) print(x) # ['t1', 't2', 't3']
