Goal: Learn to remove elements from a dictionary Goal: Learn to dynamically create dictionaries.

Assignment: Whole numbers are the numbers $1,2,3,$ and so on$.$ Write some code that assigns

to inverted a dictionary that maps the first $n$ whole numbers to their inverse $(\frac{1}{n}).$squares $=\{\}$ square $=$ number $**2$return squares

n $=5$

squares $=$ create$\_$squares$\_$dict$($n$)$Question $4$

Assignment: Assume the variable iso$\_3166$ refers to a dictionary mapping each country's name

to its Alpha$-2$ code. Write some code that deletes the element with key "East Timor" and sets its

mapped value to the new key "Timor$-$Leste".iso$\_3166["$Timor$-$Leste"$]=$ "East Timor"Question $3$
