Question

In your program use the text file decimalNumbers txt. For problem 2 you will also need decimalNumbers 1.txt. Download these files to your computer and store it in the same folder than your Python files.

a. Before calling any of the functions you need to open the file,
b. after calling the function you need to close the file.
Do not use file.readlines() in your solutions.
Define and test a value-returning function that has one parameter representing the file object. It returns a list with the float numbers in the given file sorted in ascending order.

Answer 1

Define a Python function that reads floating point numbers from a file and returns a sorted list, using file object manipulation without the use of readlines(). Open the file before and close it after invoking the function.

Step-by-step explanation:

To solve the problem, you need to define a function in Python that takes a file object as a parameter, reads the float numbers from it, and returns them sorted in ascending order. Here is an example of how you could write this function:

def sort_numbers(file):
numbers = []
for line in file:
numbers.append(float(line.strip()))
numbers.sort()
return numbers

# Usage example:
with open('decimalNumbers.txt', 'r') as file:
sorted_numbers = sort_numbers(file)
print(sorted_numbers)

Remember to open the file before calling the function and close it afterward. Since readlines() is not allowed, the function reads each line one by one, strips any whitespace or newline characters, converts them to floats, and appends them to a list. Then, it uses the list's sort() method to sort the numbers.
