Functions and Loops Mixed-Up Code Questions

Section 5.35 Functions and Loops Mixed-Up Code Questions

Checkpoint 5.35.1.

Create a function called nums_x_to_y that takes in two integer parameter, x and y and uses a for loop to create and return a list with numbers x to y. Note: ignore cases when y is not larger than x. For example, nums_x_to_y(1,10) would return [1, 2, 3, 4, 5, 6, 7, 8, 9, 10].

def nums_x_to_y(x,y):
---
def nums_x_to_y:  #paired
---
    x_to_y_list = []
---
    for num in range(x, y + 1):
---
    for num in range(y):  #paired
---
    for num in range(x, y): 
---
        x_to_y_list.append(num)
---
    return x_to_y_list

Checkpoint 5.35.2.

Create a function count_by_x_to_y that takes in two integer parameter, x and y and uses a for loop to create and return a list with numbers x to y. Note: ignore cases when y is not larger than x. Use a for loop to create and return a list with numbers up to y by skip counting by x. For example, count_by_x_to_y(5,20) should return [0, 5, 10, 15, 20].

def count_by_x_to_y(x,y):
---
def count_by_x_to_y:  #paired
---
    x_to_y_lst = []
---
    for num in range (0, y + 1, x):
---
    for num in range (0, y, x+1):  #paired
---
        x_to_y_lst.append(num)
---
        x_to_y_lst += num  #paired
---
    return x_to_y_lst

Checkpoint 5.35.3.

Create a function called countdown that takes in one integer parameter seconds and creates a list of numbers that counts down from seconds to 1, and then returns that list. Note: seconds must be greater than or equal to 1. For example, countdown(3) would return [3, 2, 1].

def countdown(seconds):
---
def countdown():  #paired
---
    countdown_lst = []
---
    while seconds > 0:
---
        countdown_lst.append(seconds)
---
        seconds -= 1
---
    return countdown_lst

Checkpoint 5.35.4.

Create a function add_odds_or_floor_division that takes in a parameter num_list and loops through the num_list. If the number in num_list is odd, it gets added to result. Otherwise, it gets divided from the result, having the result be the floor value. Then, return result. For example, add_odds_or_floor_division([-3, -5, -2, -9, 7.5, 10001, -5.3]) would return -1887.0.

def add_odds_or_floor_division(num_list):
---
def add_odds_or_floor_division():  #paired
---
    result = 0
---
    for num in num_list:
---
        if num % 2 == 1:
---
        if num / 2 == 1:  #paired
---
            result += num
---
        else:
---
            result //= num
---
            result /= num  #paired
---
    return result

Checkpoint 5.35.5.

Create a function strings_chars_less_than_len that takes in a strings_list and returns a sorted new list with strings that are shorter in length than the original list. For example, strings_chars_less_than_len(['hello', 'bye', 'me', 'mississippi', 'miss']) would return [‘bye', ‘me', ‘miss'].

def strings_chars_less_than_len(strings_list):
---
Def strings_chars_less_than_len(string_list):  #paired
---
    new_strings_list = []
---
    for string in strings_list:
---
        if len(string) < len(strings_list):
---
        if string < len(strings_list):  #paired
---
            new_strings_list.append(string)
---
        else:
---
            continue
---
            break  #paired
---
    return sorted(new_strings_list)
---
    return new_strings_list.sort()  #paired

Checkpoint 5.35.6.

Create a function print_lists(nums1, nums2) that takes two lists of numbers with the same length, nums1 and nums2, and returns a list of strings in the form: “Num1: num1, Num2: num2” for each pair of items in the two lists. For example, print_lists([3, 2], [8, 4]) would return ["Num1: 3, Num2: 8", "Num1: 2, Num2: 4"].

def print_lists(nums1, nums2):
---
    out_list = []
---
    for i in range(len(nums1)):
---
    for i in range(nums1):  #paired
---
    for val1 in nums1:
        for val2 in nums2: 
---
        val1 = nums1[i]
        val2 = nums2[i]
---
        out = "Num1: " + str(val1) + ", Num2: " + str(val2)
---
        out = "Num1: " + val1 + ", Num2: " + val2  #paired
---
        out_list.append(out)
---
    return out_list

Checkpoint 5.35.7.

Create a function sum_lists(nums1, nums2) that takes two lists of numbers with the same length, nums1 and nums2, and returns a list of the totals of the two numbers for each pair of items in the two lists. For example, sum_lists([3, 2], [8, 4]) would return [11, 6].

def sum_lists(nums1, nums2):
---
    out_list = []
---
    for i in range(len(nums1)):
---
    for i in range(nums1):  #paired
---
    for val1 in nums1:
        for val2 in nums2: 
---
        val1 = nums1[i]
        val2 = nums2[i]
---
        total = val1 + val2
---
        out_list.append(total)
---
        out_list += total  #paired
---
    return out_list
