I am reading values a SQLITE database and want to create a dictionary based on the values in a specific column. The dictionary would have a key of the text string from the database, and the value would be a count of the number of times that the string has appeared. Problem is, I don’t know what the values are in the DB until I run the select statement.
In short, how can I build a count of the number of times each string appears in a column, using a dictionary?
As an example, the below table would produce the dictionary underneath:
| Cities |
|---|
| London |
| Manchester |
| London |
| Manchester |
| Birmingham |
| Reading |
| Reading |
| Reading |
| Londn |
| Newcastle |
| Newcastle |
|London|2|
|Manchester|2|
|Birmingham|1|
|Reading|3|
|Londn|1|
|Newcastle:2|
