Then it reads the file one line at a time and creates a new friends database to return. Like in the previous function, each line will contain a friend's name followed by a tab, then the friend's height, and then a newline. Sample calls should look like this: >>> load friendsdb("friendsdb.tsv") [{'name': ' bimmy', 'height': 600}, {'name': 'Ian Donald Calvin Euclid Zappa', height': 175}]
