Section5.37Functions and Loops Write Code Questions
Activity5.37.1.
Write a function called list_starts_with_a that takes in lst as a parameter and returns a new list with the words from lst that start with “a”. For example, list_starts_with_a(["alphabet", "apple", "banana", "coding", "amazing"]) would return ["alphabet", "apple", "amazing"].
def list_starts_with_a(lst):
list_a = []
for word in lst:
if word.startswith('a'):
list_a.append(word)
return list_a
print(list_starts_with_a(["alphabet", "apple", "banana", "coding", "amazing"]))
Write a function called sentence_without_vowels that takes in string as a parameter and returns a new string that consists of only characters that are not vowels. For example, sentence_without_vowels('apple') would return "ppl".
Write a function called draw_square that takes in num as a parameter and returns a string that consists of a square made of “*” with the dimensions num times num. Note: ignore values that are less than or equal to zero. For example, draw_square(4) would return "****\n****\n****\n****".
def draw_square(num):
string1 = ""
for i in range(num):
if i < (num - 1):
string1 += "*" * num + "\n"
else:
string1 += "*" * num
return string1
print(draw_square(4))
Write a function called check_prime_num that takes in num as a parameter and returns True if num is a prime number and False otherwise. For the purposes of this question, there is no need to test for values of num that are less than two. For example, check_prime_num(5) should return True.
Write a function called factorial that takes in num as a parameter and returns the factorial value. Ignore checking numbers that are less than 1. For example, factorial(5) would return 120.
