nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

Cutting text from one field to add to another field.

NicoMcBrain

I have data in one field that looks like this 1 - EV-32818RC and it ranges with the first number reaching at max 74031 - EV-33160RC. What I am needing is the numbers before the hyphen cut and moved to another Field, only leaving behind the EV-*******. Both fields are text if that helps any.

I would use split()

field.split()[0] for the first part and field.split()[-1] for the last part, assuming there is always a space before and after the hyphen.

yes there is a space around the hyphen(both sides). This solution worked perfectly, I would like to understand the semantics behind how it worked. Like why [0] and [-1]

dgiersz_cuyahoga

split() creates a list of the strings using whitespace as the default separator.

"74031 - EV-33160RC" becomes ['74031', '-', 'EV-33160RC']

You access contents of a list using the list index where 0 is the first item and -1 is the last item (The negative means start at the end and go through the list backwards)

field[1] and field [-2] in this case should both yield '-'

Thank you.
