Write the regular expression that will match all open compound words (separated by a space) starting with the word best and with a second word that begins with a b. Use the character class \s in your expression.

Example

txt = "best buy best car best friend best-boy bestguest best dressed best bet best man best deal best boyfriend"
pattern = "yourregularexpressionhere"

re.findall(pattern, txt) ➞ ["best buy", "best bet", "best boyfriend"]

Notes

• You don't need to write a function, just the pattern.
• Do not remove import re from the code.
• Find more info on RegEx and character classes in Resources.
