method

You want to have a buffer of 1,000 feet for the parks, dissolved to just the UNIT_NAME, AGENCY_NAME, and LABEL_NAME. To get this you will be typing in the in_features, out_featuers, buffer_distance, dissolve_option, and dissolve_field paramaters. The in_features, out_features, and buffer_distance are the first 3 parameters, but the dissolve_option and dissolve_field are the 6th and 7th parameters. To make sure they are in those positions you will type a pair of single or double quotes in the 4th and 5th parameters. This signifies to the function that those optional parameters are blank, just as if they weren’t entered; and allows you to enter parameters after them. Type in “CPAD_2020b_Units_Oakland”,”CPAD_2020b_Units_Oakland_1000ft”,”1000 FEET”, “”,””,”LIST”,[“UNIT_NAME”,”AGNCY_NAME”,”LABEL_NAME”] And press Enter
