how to create a list with a defined length and items in python

Question

I have a length as 5 and my_name=A

I want to create a list with a length of 5 and the items should contain my_name

My desired output is,

length=5
my_name="A"
desired_list=["A1","A2","A3","A4","A5"]

I tried adding like below,

desired_list=[]
for i in range(length):
    desired_list.append(my_name+str(i+1))

But I want a solution in a single line.

How did you try and solve this yourself? Did you google search for solutions? — Chris_Rands, Oct 05 '17 at 09:01

I tried adding elements through iteration. I am looking for a solution with a single line — Pyd, Oct 05 '17 at 09:02

Looks like you want to use a list comprehension:

length = 5
my_name = "A"
desired_list = [my_name+str(i+1) for i in range(length)]
