It matches the boundary of a word, such as a space, but it is a '0' length character. The matched string does not include the delimiter. If '\ s' is used for matching, the matched string contains the separator.
Example:

>>> Re. findall (R' \ BBC \ B ', S) # Matches a separate word 'bc', but does not match when it is part of other words.
['Bc'] # Only the independent 'bc' is found'

Many people may not be very familiar with the optical fiber cabling technology. This article will give you a comprehensive introduction to this technology, the advantages of the optical fiber cabling technology and the problems that need to be paid attention to in practical application will also be explained.
