Get a List of Numbers as Input from the User: Pythonic Solution

When attempting to retrieve a list of numbers from a user using input() or raw_input(), you may encounter unexpected results due to Python's tendency to interpret input as strings. To avoid this issue and obtain a list of integers, employ a more Pythonic approach using list comprehension and input splitting.

a = [int(x) for x in input().split()]

Example:

>>> a = [int(x) for x in input().split()]
3 4 5
>>> a
[3, 4, 5]

This concise solution utilizes:

• Splitting input: Split the user's input string into a list of substrings using the split() method. By default, it splits at whitespace characters.
• Casting to integers: Employ list comprehension to convert each substring into an integer, ensuring that the resulting list contains numeric values.

By utilizing this approach, you can effortlessly capture a list of numbers from the user in Python, eliminating the need for complex regular expressions or additional parsing steps.
