Using the dictionary:

d = {'1': 'a'}

How can I extract the value ‘a’ using the jmespath library in Python?

The following attempts do not work:

import jmespath

value = jmespath.search("1", d) 
# throws jmespath.exceptions.ParseError: invalid token
value = jmespath.search("'1'", d) 
# returns the key '1' instead of the value 'a'
