Elements in a range (python)

Question

I am stuck on a python homework question and I was wondering if I could get some help. The question goes like this:

"Write a program that first gets a list of integers from input. That list is followed by two more integers representing lower and upper bounds of a range. Your program should output all integers from the list that are within that range (inclusive of the bounds).

The bounds are 0-50, so 51 and 200 are out of range and thus not output.

For coding simplicity, follow each output integer by a comma, even the last one. Do not end with newline."

Answer 1

This will help you

# Get list of integers from input

lst = list(map(int, input().split()))

# Get lower and upper bounds

lower, upper = map(int, input().split())

# Filter integers within range

filtered = [x for x in lst if lower <= x <= upper and 0 <= x <= 50]

# Output filtered integers

for i in range(len(filtered)):

if i == len(filtered) - 1:

print(filtered[i], end="")

else:

print(filtered[i], end=", ")

The first line gets a list of integers from input by reading a line of input, splitting it into a list of strings using split(), and converting each string to an integer using map(int, ...). The result is a list of integers lst. The second line gets the lower and upper bounds by reading another line of input and converting the two strings to integers using map(int, ...). The result is two integer variables lower and upper.The third line filters the integers in the list lst that are within the specified range (inclusive of the bounds) and are also within the range of 0-50 using a list comprehension. The result is a new list filtered containing only the filtered integers.The fourth and fifth lines output the filtered integers, separated by commas. The loop iterates over the indices of the filtered list and prints each element followed by a comma (except for the last element, which is printed without a comma). The end argument of the print() function is set to an empty string to prevent it from adding a newline character after each print statement.

I hope this helps you to understand the problem.

My solution with comment to help you understand it better.

# First, we will define a function that takes in a list of integers, a lower bound, and an upper bound as parameters.

def find_range(int_list, lower_bound, upper_bound):

# We will create an empty list to store the integers that are within the given range.

in_range = []

# We will loop through the list of integers.

for num in int_list:

# If the number is greater than or equal to the lower bound and less than or equal to the upper bound, we will add it to the in_range list.

if num >= lower_bound and num <= upper_bound:

in_range.append(num)

# We will join the list of integers in the in_range list into a string, with each integer separated by a comma.

in_range_string = ",".join(str(num) for num in in_range)

# Finally, we will return the string.

return in_range_string

# We will create a list of integers.

int_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20]

# We will set the lower and upper bounds.

lower_bound = 5

upper_bound = 15

# We will call the find_range function and pass in the list of integers, the lower bound, and the upper bound.

in_range_string = find_range(int_list, lower_bound, upper_bound)

# We will print the string.

print(in_range_string)

# Output: 5,6,7,8,9,10,11,12,13,14,15

Answer 3

Writing this as code is relatively simple. The instruction outlines everything that you have to do, all you need to do is translate it into python syntax. Here's a start:

array = []

for i in range(5): # adjust the range according to the question

temp = input("Provide the " + str(i+1) + "th number: ")

array.append(temp)

lower_bound = input("Provide a lower bound: ")

upper_bound = input("Provide an upper bound: ")

This will take in the necessary inputs as provided by the user. Now you need to figure out how to check if the integers inside your array are within the bounds. I recommend you use a loop, and check each individual value in the array against the lower and upper bounds. Good luck.
