Hi Pablo, While playing around with the function you gave me(get_data)...i was thinking to do something like below. For each line create a dictionary then append that dictionary to a list...but before i even get to that part i get the below error and while researching it i am unable to figure out what is going on... could you point me in the right direction ?
