          """
          Adds one or more variables to the cache.
  
          :param args:
              Variables can be specified by two consecutive arguments where the
              first argument is a key and the second one the corresponding value.
              For example:
  
              ```
              put('a', 1, 'b', False)
              ```
  
              would add two variables to the cache where the value of _a_ would
              be 1 and the value of _b_ would be False.
          :param kwargs:
              Keyword arguments to be added to the cache, which are name value
              pairs like standard keyword named arguments in Python. For example:
  
              ```
              put(a=1, b=False)
              ```
  
              would add two variables to the cache where the value of _a_ would
              be 1 and the value of _b_ would be False.
