Answer:
A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}
Explanation:
Since <em>python does not use type when declaring a variable</em>, you must make sure you make your variables correctly or else it won't compile correctly. Lists use braces[]; Strings use quotes, "" or ''; Integers are just declared with a number(s); Dictionaries use brackets{} and inside are <u>attributes of something</u>. For instance, you can use dictionaries to describe ages, {'"Bryan": 6, "Alex": 13, etc.} <u>Sort of like a json file</u>. Dictionaries also tend to use <u>uppercase letters</u> when describing something. The only answer that has all the attributes correct is A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}

Answer:
1)
n = int(input("Please enter the length of the sequence: "))
print("Please enter your sequence")
product = 1
for i in range(n):
val = int(input())
product *= val
print("The geometric mean is: %.4f"%pow(product,1/n))
2)
print("Please enter a non-empty sequence of positive integers, each one is in a separate line. End your sequence by typing done:")
product = 1
val = input()
n = 0
while(val!="done"):
product *= int(val)
n += 1
val = input()
print("The geometric mean is: %.4f"%pow(product,1/n))
