Need help to get the string after the third “_”

Example

r_a_B_TEXAS
r_asda_Bads_DALLAS
r_asda_Bads_DISNEY_LAND
rdd_asda_Bads_Florida_MIAMI_NICE

I need this output

TEXAS
DALLAS
DISNEY_LAND
Florida_MIAMI_NICE

Thanks

With split function

hostname.split(‘_’)[3] I only get the third value but for DISNEY_LAND I only get DISNEY and wanna have everything DISNEY_LAND
