Python Programming Puzzles: Exercise-80 with Solution

Write a Python program to round each float in a given list of number up to the next integer and return the running total of the integer squares.

Input:  
[2.6, 3.5, 6.7, 2.3, 5.6]
Output:
[9, 25, 74, 83, 119]

Input:  
[301.1, 401.4, -23.1, 13554122.0, 10201.0101, 10000000.0]
Output:
[91204, 252808, 253337, 183714223444221, 183714327525025, 283714327525025]

Pictorial Presentation:

Python: Round each float in a list of numbers up to the next integer and return the running total of the integer squares.

Sample Solution:

Python Code:

def test(nums):
    from math import ceil
    running_squares = []
    tot = 0
    for v in nums:
        tot += ceil(v) ** 2
        running_squares.append(tot)
    return running_squares
   
nums = [2.6, 3.5, 6.7, 2.3, 5.6]
print("List of numbers:",nums)
print("Round each float of the said list up to the next integer and return the running total of the integer squares:")
print(test(nums))
nums = [301.1, 401.4, -23.1, 13554122.0, 10201.0101, 10000000.0]
print("\nList of numbers:",nums)
print("Round each float of the said list up to the next integer and return the running total of the integer squares:")
print(test(nums))

Sample Output:

List of numbers: [2.6, 3.5, 6.7, 2.3, 5.6]
Round each float of the said list up to the next integer and return the running total of the integer squares:
[9, 25, 74, 83, 119]

List of numbers: [301.1, 401.4, -23.1, 13554122.0, 10201.0101, 10000000.0]
Round each float of the said list up to the next integer and return the running total of the integer squares:
[91204, 252808, 253337, 183714223444221, 183714327525025, 283714327525025]

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

The os and os.path modules.

The __file__ constant

os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")

os.path.dirname(path) (returns "the directory name of pathname path")

os.getcwd() (returns "a string representing the current working directory")

os.chdir(path) ("change the current working directory to path")
