Python: Create the largest possible number using the elements of a given list of integers
Python List: Exercise - 179 with Solution
Write a Python program to create the largest possible number using the elements of a given list of positive integers.
Sample Solution:
Python Code:
def create_largest_number(lst):
if all(val == 0 for val in lst):
return '0'
result = ''.join(sorted((str(val) for val in lst), reverse=True,
key=lambda i: i*( len(str(max(lst))) * 2 // len(i))))
return result
nums = [3, 40, 41, 43, 74, 9]
print("Original list:")
print(nums)
print("Largest possible number using the elements of the said list of positive integers:")
print(create_largest_number(nums))
nums = [10, 40, 20, 30, 50, 60]
print("\nOriginal list:")
print(nums)
print("Largest possible number using the elements of the said list of positive integers:")
print(create_largest_number(nums))
nums = [8, 4, 2, 9, 5, 6, 1, 0]
print("\nOriginal list:")
print(nums)
print("Largest possible number using the elements of the said list of positive integers:")
print(create_largest_number(nums))
Sample Output:
Original list: [3, 40, 41, 43, 74, 9] Largest possible number using the elements of the said list of positive integers: 9744341403 Original list: [10, 40, 20, 30, 50, 60] Largest possible number using the elements of the said list of positive integers: 605040302010 Original list: [8, 4, 2, 9, 5, 6, 1, 0] Largest possible number using the elements of the said list of positive integers: 98654210

Python: Tips of the Day
Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:
Example:
def tips_check_prop(fn, prop): return lambda obj: fn(obj[prop]) check_age = tips_check_prop(lambda x: x >= 25, 'age') user = {'name': 'Owen', 'age': 25} print(check_age(user))
