Hello I am trying to add a str method to a Set ADT implementation to
allow a user to print the contents of a set. However the resulting
string should look like that of a list. except I am suppose to use curly
brackets to surround the elements.
For an example...
set1 = Set()
print(set1)
{}
Question is how do you implement the "curly brackets" in my str method?
Curly brackets are just characters like any other...
>>> print( '{', 42, '}' )
This is what I have so far...
def __init__( self, *initElements ):
self._theElements = list()
def __str__(self):
return self._theElements
You are returning a list. But __str__() is supposed to return a string.
You need to create a string representation of your data. There are many
ways to do that depending on what you want it to look like or contain.
