Assessment: Week Three

rainfall_mi is a string that contains the average number of inches of rainfall in Michigan for every month (in inches) with every month separated by a comma. Write code to compute the number of months that have more than 3 inches of rainfall. Store the result in the variable num_rainy_months. In other words, count the number of items with values > 3.0.

Hard-coded answers will receive no credit.

rainfall_mi = "1.65, 1.46, 2.05, 3.03, 3.35, 3.46, 2.83, 3.23, 3.5, 2.52, 2.8, 1.85"
months = rainfall_mi.split(",")
count = 0
for i in months:
if float(i) > 3.0:
count += 1

num_rainy_months = count

The variable sentence stores a string. Write code to determine how many words in sentence start and end with the same letter, including one-letter words. Store the result in the variable same_letter_count.

Hard-coded answers will receive no credit.

sentence = """students flock to the arb for a variety of outdoor
activities such as jogging and picnicking"""
sen = sentence.split()
count = 0
# Write your code here.
for i in sen:
if i[0] == i[len(i)-1]:
count += 1
same_letter_count = count

Write code to count the number of strings in list items that have the character w in it. Assign that number to the variable acc_num.

HINT 1: Use the accumulation pattern!

HINT 2: the in operator checks whether a substring is present in a string.

Hard-coded answers will receive no credit.

items = ["whirring", "wow!", "calendar", "wry", "glass", "", "llama","tumultuous","owing"]
count = 0
for i in items:
if 'w' in i:
count += 1
acc_num = count

Write code that counts the number of words in sentence that contain either an “a” or an “e”. Store the result in the variable num_a_or_e.

Note 1: be sure to not double-count words that contain both an a and an e.

HINT 1: Use the in operator.

HINT 2: You can either use or or elif.

Hard-coded answers will receive no credit.

sentence = "python is a high level general purpose programming language that can be applied to many different classes of problems."
sen = sentence.split()
count = 0
for i in sen:
if 'a' in i or 'e' in i:
count += 1
num_a_or_e = count

Write code that will count the number of vowels in the sentence s and assign the result to the variable num_vowels. For this problem, vowels are only a, e, i, o, and u. Hint: use the in operator with vowels.

s = "singing in the rain and playing in the rain are two entirely different situations but both can be fun"
vowels = ['a','e','i','o','u']
count = 0
# Write your code here.
for i in s:
if i in vowels:
count += 1

num_vowels = count
