Answers should be legal Python code, including indentation. Use the underscore _ to show a space.
Special functions: print(), range(), sqrt(), str()
Assume you have a list of letters X. Write code to count the number of times the letter "B" appears in the list.

Use: variables, loops, if[2]

Test Using:
X = []
X = ['B','a','z']
X = ['B','B','B']
A list contains a series of attacks on an enemy. The list looks like [1,2,3,1,1,2,...] where each element in the list is a number that means a type of attack:

1 is a light attack, taking 1HP
2 is a medium attack taking 4HP
3 is a strong attack taking 15HP

Write code to calculate the total amount of HP damage caused by all the attacks.

Use: variables, loops, if[3]

Test Using:
attacks = [1,2,3]
attacks = [1,2,3,3,2,1]
attacks = [19,41,1]
Assume you have a list variable LIST. Count the number of items in LIST and print the result.

Use: loops, variables[2]

Test Using:
LIST = ['a','b','c']
LIST = [1,2,3,4,5,6]
LIST = []
Do the sum 92 + 29 in code and store the result

Use: variables[1]
A rectangle has sides of 7 and 2. Create variables for the sides of the shape and then calculate its area

Use: variables[2]
Print each number from 9 to 19

Use: loops[2]
A list contains a series of attacks on an enemy. The list looks like [1,2,3,1,1,2,...] where each element in the list is a number that means a type of attack:

1 is a light attack, taking 2HP
2 is a medium attack taking 4HP
3 is a strong attack taking 13HP

Write code to calculate the total amount of HP damage caused by all the attacks.

Use: variables, loops, if[3]

Test Using:
attacks = [1,2,3]
attacks = [1,2,3,3,2,1]
attacks = [19,41,1]
