I have origin-destination lines and I'm looking for intra-city lines or lines whose origin and destination are in the same city.
A sample intra-city feature would be
"Quezon_City to Quezon_City" and inter-city would be
"Quezon_City to CALOOCAN_CITY".
I'd like some help in writing an expression that selects all features whose string before
"to" is the same with the string after it using Python or Expression Builder.
