Introduction
Writing to a JSON file
Instruction
Well done! You may be wondering whether every type of Python object can be saved as a JSON object. Unfortunately, no. There are many objects that can be converted to JSON; we've listed a few below with their JSON equivalents:
| Python | JSON |
|---|---|
| dict | object |
| list | array |
| str | string |
| int | long number |
| float | number |
| True | true |
| False | false |
| None | null |
Sometimes, we can get into trouble when converting an object. For example, we could have the following problem if we tried to convert a Python set.
Exercise
Create a set named random that contains the values 3.14, 273, and 'a'. Then, call the json.dumps() function with this object as an argument.
Will we get an error? If so, what kind of error?
Stuck? Here's a hint!
Create a random set:
random = {3.14, 273, 'a'}
Then, use json.dumps(random).
