Cell_type python

I'm learning python and I've run into this in the Spyder IDLE:

"cell_type": "code",

   "execution_count": 1,

   "metadata": {},

   "outputs"

"data": {
      "text/plain":
}

"output_type".

**Ejemplo**


       "cell_type": "code",
       "execution_count": 3,
       "metadata": {},
       "outputs": [
        {
         "data": {
          "text/plain": [
           "625"
          ]
         },
         "execution_count": 3,
         "metadata": {},
         "output_type": "execute_result"
        }
       ],
       "source": [
        "(2+3)**4"
       ]
      }

What does each field mean?
