Python: Create the smallest possible number using the elements of a given list of integers

Python List: Exercise - 180 with Solution

Write a Python program to create the smallest possible number using the elements of a given list of positive integers.

Visual Presentation:

Sample Solution:

Python Code:

``````# Define a function 'create_smallest_number' that takes a list 'lst' as input.
def create_smallest_number(lst):
# Check if all elements in the list are 0, return '0' if true.
if all(val == 0 for val in lst):
return '0'

# Sort the elements in the list in ascending order based on a custom key.
# The key is a lambda function that computes a string value for each element.
# The length of the computed string is adjusted to ensure proper sorting.
result = ''.join(sorted((str(val) for val in lst), reverse=False,
key=lambda i: i*( len(str(min(lst))) * 2 // len(i)))
)
return result

# Create a list of positive integers.
nums = [3, 40, 41, 43, 74, 9]
print("Original list:")
print(nums)

# Call the 'create_smallest_number' function to find the smallest possible number
# using the elements of the list.
print("Smallest possible number using the elements of the said list of positive integers:")
print(create_smallest_number(nums))

# Repeat the process for two more sets of input data.
nums = [10, 40, 20, 30, 50, 60]
print("\nOriginal list:")
print(nums)
print("Smallest possible number using the elements of the said list of positive integers:")
print(create_smallest_number(nums))
nums = [8, 4, 2, 9, 5, 6, 1, 0]
print("\nOriginal list:")
print(nums)
print("Smallest possible number using the elements of the said list of positive integers:")
print(create_smallest_number(nums))
```
```

Sample Output:

```Original list:
[3, 40, 41, 43, 74, 9]
Smallest possible number using the elements of the said list of positive integers:
3404143749

Original list:
[10, 40, 20, 30, 50, 60]
Smallest possible number using the elements of the said list of positive integers:
102030405060

Original list:
[8, 4, 2, 9, 5, 6, 1, 0]
Smallest possible number using the elements of the said list of positive integers:
01245689
