Hacks
- Add a couple of records to the InfoDb
- Try to do a for loop with an index
- Pair Share code somethings creative or unique, with loops and data. Hints...
- Would it be possible to output data in a reverse order?
- Are there other methods that can be performed on lists?
- Could you create new or add to dictionary data set? Could you do it with input?
- Make a quiz that stores in a List of Dictionaries.
for index in range (len(InfoDb)):
print_data(InfoDb[index])
mylist = [1, 2, 3, 4, 5]
mylist.reverse()
mylist
[5, 4, 3, 2, 1]
a = [10, 20, 30, 40, 50]
len(a)
grades = ['A', 'B', 'C', 'D', 'F']
grades.sort(reverse=True)
print(grades)
grades = ['A', 'B', 'C', 'D', 'F']
grades.pop(1)
