Hello all. I am really new to python but have been learning. This is my first post and hopefully someone will be able to help me out. I have a .dbf that contains a huge list (59000 records) of geologic units and their corresponding quadrangles. Each geologic unit can be found in multiple quads too. I want to develop a program that asks a user to input what geologic unit their looking for and output the corresponding quadrangle(s). What would be the best way for me to approach this problem? Thanks for any input.
