Regular expression example not clear.

Using the data shown, it is not clear the difference between using "X" vs. "^X" as both results are the same.

Current text:
re.search("^X", "A\nB\nX", re.MULTILINE) # Match

re.search("^X", "A\nB\nX", re.MULTILINE)
<re.Match object; span=(4, 5), match='X'>
re.search("X", "A\nB\nX", re.MULTILINE)
<re.Match object; span=(4, 5), match='X'>

Recommended text change:
re.search("^X", "AX\nBX\nXC", re.MULTILINE) # Match

re.search("^X", "AX\nBX\nXC", re.MULTILINE) # Match
<re.Match object; span=(6, 7), match='X'>
re.search("X", "AX\nBX\nXC", re.MULTILINE) # Match
<re.Match object; span=(1, 2), match='X'>

With the ^ the search picks up the X at the beginning of the line at position 6.
With no ^ the search picks up the X at position 1.

Note that that part of the documentation ("search() vs. match()") is describing the differences between re.match and re.search:

re.match("X", "A\nB\nX", re.MULTILINE)  # No match
re.search("^X", "A\nB\nX", re.MULTILINE)  # Match

Your example uses re.search for both.
