[Suggestion] 26. Value types 1. Displaying the player's health and energy - doc of str() to be more specific

[psstoyanov]

Suggestion: With 26. Value types 1. Displaying the player's health and energy, the documentation on str() is good but it requires for the person to read through the entire description.

Could the documentation have the argument listed as well, ie: String str(argument) to allow for the usage of the method to be obvious at a glance?
