How to append string into list using list comprehension

Question

Ex:

a = []
a.append('Hello')

Which will give the output: ['Hello']

Could you please tell me How to do the same using list comprehension?

Answer 1

If you only have

a = []
a.append('Hello')

as you know, it would be most practical to simply do

a = ['Hello']

But if you want to append multiple 'Hello' s to the list, you can do it like

a = ['Hello' for _ in range(amount)]

Where the amount variable should be replaced with the number of 'Hello' s you want in the list.

Another way to do the above is

a = ['Hello'] * amount

Answer 2

You actually do not need to use list comprehension here. Just simply do:

a=['Hello']

You can do it by doing

a = ['Hello' for i in range(1)]

But it will just lead to more memory allocation than needed.
