1.Coding question 1 Divisible By Ten
Create a function named divisible_by_ten() that takes a list of numbers named nums as a parameter.
Return the count of how many numbers in the list are divisible by 10.
def divisible_by_ten(nums):
count = 0
for number in nums:
if (number % 10 == 0):
count += 1
return count
print(divisible_by_ten([20, 25, 30, 35, 40]))
2.Coding question 2 Greetings
Create a function named add_greetings() which takes a list of strings named names as a parameter.In the function, create an empty list that will contain each greeting. Add the string 'Hello, ' in front of each name in names and append the greeting to the list.Return the new list containing the greetings.
def add_greetings(names):
new_list = []
for name in names:
new_list.append("Hello, " + name)
return new_list
print(add_greetings(["Owen", "Max", "Sophie"]))
3.Coding question 3
Write a function called delete_starting_evens() that has a parameter named my_list.
The function should remove elements from the front of my_list until the front of the list is not even. The function should then return my_list.
For example if my_list started as [4, 8, 10, 11, 12, 15], then delete_starting_evens(my_list) should return [11, 12, 15].
Make sure your function works even if every element in the list is even!
#Write your function here (Can you find the problem?)
def delete_starting_evens(my_list):
for num in my_list:
if num % 2 == 0:
my_list.remove(num)
else:
break
return my_list
print(delete_starting_evens([4, 8, 10, 11, 12, 15]))
# =>[8, 11, 15]
print(delete_starting_evens([4, 8, 10]))
# =>[8]
#This is the way we solved it:
def delete_starting_evens(my_list):
while (len(my_list) > 0 and my_list[0] % 2 == 0):
my_list = my_list[1:]
return my_list
print(delete_starting_evens([4, 8, 10, 11, 12, 15]))
# =>[11, 12,15]
print(delete_starting_evens([4, 8, 10]))
# =>[]
4.Coding question 4 Odd Indices
Create a function named odd_indices() that has one parameter named my_list.
The function should create a new empty list and add every element from my_list that has an odd index. The function should then return this new list.
For example, odd_indices([4, 3, 7, 10, 11, -2]) should return the list [3, 10, -2].
def odd_indices(my_list):
new_my_list = []
for i in range(len(my_list)):
if i % 2 == 1:
new_my_list.append(my_list[i])
return new_my_list
print(odd_indices([4, 3, 7, 10, 11, -2]))
# =>[3, 10, -2]
#Here is this solution:
def odd_indices(my_list):
new_list = []
for index in range(1, len(my_list), 2):
new_list.append(my_list[index])
return new_list
print(odd_indices([4, 3, 7, 10, 11, -2]))
# =>[3, 10, -2]
5.Coding question 5 Exponents
Create a function named exponents() that takes two lists as parameters named bases and powers. Return a new list containing every number in bases raised to every number in powers.
For example, consider the following code.exponents([2, 3, 4], [1, 2, 3])
def exponents(bases, powers):
my_list = []
for num1 in bases:
for num2 in powers:
my_list.append(num1**num2)
return my_list
print(exponents([2, 3, 4], [1, 2, 3]))
# =>[2, 4, 8, 3, 9, 27, 4, 16, 64]
#Here is how we solved this one:
def exponents(bases, powers):
new_list = []
for base in bases:
for power in powers:
new_list.append(base ** power)
return new_list
print(exponents([2, 3, 4], [1, 2, 3]))
# =>[2, 4, 8, 3, 9, 27, 4, 16, 64]
