Please tell me the data type of the for loop iterator based on the context.

thing = "As you lead us onto fame and honor, FIGHT FIGHT FIGHT!
Will be our cry. So give us a yell (ho!) the Purple and the Gold, Victory for UNI! U-N-I Fight! U-N-I Fight!"

1. 
for element in thing:

What is element?

2. 
thing = thing.split()

for element in thing:

What is element?

3. 
thing = thing.split()
for element in thing:
	for something in element:

What is something?

---------------------




4. 
thing = "As you lead us onto fame and honor, FIGHT FIGHT FIGHT!
Will be our cry. So give us a yell (ho!) the Purple and the Gold, Victory for UNI! U-N-I Fight! U-N-I Fight!"

How would I use a dictionary to count the number of words?  Write a function that takes in a string and prints each word followed by a count.




5. 
listOfGrades = [70.5, 81.2, 77.4, 90, 85]

How would I find the average of these grades?  Write a function that takes in a list and returns the average.





6. 
Bob = {'France','Germany','Canada'}
Alice = {'Canada','Jamaca','Brazil'}

How would I write a program to find places in common that both Bob and Alice have traveled?  Write a function that takes in two sets and returns a new set of places in common.
