The output would be “N match found”
Justification : re.search( ) rill attempt the pattern throughout the string, i ntil it finds a match. re.match( ) on the other hand, only attempts the pattern at the very start of the string.
Example :
>>>re.match(“d”, “abcdef’) # No match >>>re.search(“d”, “abcdef’) # Match
