Numbers in Strings

Create a function that takes a list of strings and returns a list with only the strings that have numbers in them. If there are no strings containing numbers, return an empty list.

Examples

num_in_str(["1a", "a", "2b", "b"]) ➞ ["1a", "2b"]

num_in_str(["abc", "abc10"]) ➞ ["abc10"]

num_in_str(["abc", "ab10c", "a10bc", "bcd"]) ➞ ["ab10c", "a10bc"]

num_in_str(["this is a test", "test1"]) ➞ ["test1"]

Notes

• The strings can contain white spaces or any type of characters.
• Bonus: Try solving this without RegEx.
