--description--

Delete your shift variable. Then, declare a new variable called custom_key and assign the value of the string 'python' to this variable.

--hints--

You should delete the shift variable and its value.

js
({ test: () => assert.isFalse(__userGlobals.has("shift")) })

You should declare a variable called custom_key.

js
({ test: () => assert(__userGlobals.has("custom_key")) })

You should assign the string 'python' to your custom_key variable.

js
({ test: () => assert.equal(__userGlobals.get("custom_key"), "python") })
