I need to import CSV file which contains all values in one column although it should be on 3 different columns.

The value I want to split is looking like this "2020-12-30 13:17:00Mojito5.5". I want to look like this: "2020-12-30 13:17:00 Mojito 5.5"

I tried different approaches to splitting it but I either get the error " Dataframe object has no attribute 'split' or something similar.

Any ideas how I can split this?
