You can try this on the interactive interpreter.
>>> re.match('hi$', 'xihi')
>>> re.search('hi$', 'xihi')
<_sre.SRE_Match object at 0x13FF7100>

Although, I think match does not work since match
only starts searching at the start of the string
while search looks for the pattern anywhere in the string.

>>> re.match('x.hi$', 'xihi')
<_sre.SRE_Match object at 0x15693BF0>

I guess you can consider re.match's pattern to be 
prefixed with '^'.
