str
str([object])
Returns a string containing a nicely printable representation of an
object. For strings, this returns the string itself. The difference
with repr(object) is that str(object) does not always attempt to
return a string that is acceptable to eval; its goal is to return a
printable string. If no argument is given, returns the empty string,
''.
To make this function work on your own classes, implement the __str__ method. If __str__ isn’t defined, this function falls back on __repr__.
