2,710 PointsBummer: Try Again. How can I debug the code in my workspace?
How can I feed the string into str and see the results?
Thinking, pls verify, print(S.str(['.', '.', '.']))
Thank you in advance...
class Letter:
code = []
def __init__(self, pattern=None):
self.pattern = pattern
def __str__(self, pattern):
for item in pattern:
if item is '.':
code.append = 'dot'
elif item is '_':
code.append = 'dash'
return ('-'.join(code))
class S(Letter):
def __init__(self):
pattern = ['.', '.', '.']
super().__init__(pattern)

And here's a few hints:
- this method shouldn't take an argument (just the "self" parameter)
- when you refer to "pattern", be sure to use the "
self.
" prefix - instead of the identity operator ("is"), you probably want to use the equality comparison ("==")
- append is a method, so the argument should go in parentheses after the method name

2,710 PointsI'm getting a SyntaxError: Can't assign the function call pointing to code.append(item) = 'dash' when I run in my Workspace
class Letter: code = [] def init(self, pattern=None): self.pattern = pattern
def __str__(self):
for item in self:
if item == '.':
code.append(item) = 'dot'
elif item == '_':
code.append(item) = 'dash'
print(code)
return ('-'.join(code))
class S(Letter): def init(self): pattern = ['.', '.', '.'] super().init(pattern)

231,275 PointsMethod calling syntax doesn't use an assignment operator:
code.append(item) = 'dot' # instead of this
code.append('dot') # try this
And remember, "self" is the object, the pattern is "self.pattern".

3,572 PointsWhen I run my code in PyCharm I get the output, "dot-dot-dot," which I thought is what we're looking for. Why when I run it in the code challenge it says the output is, "dash-dash-dash-dot-dash-dash-dot-dot-dot-dot?"
