231,059 PointsThere's a few issues:
- there should be a space after the keyword "def"
- the instructions say that the "method should accept self and one argument"
- the method code lines need to be indented more than the "def" line
- the instructions say to "Convert the argument to an int and return it."

10,080 PointsYes, I don't understand why they insisted on using a special keyword like "int." I would have rather used something else more appropriate like maybe "init." Or anything along those lines
Steven Parker
231,059 PointsThe "int" specified with the class is necessary, and is the keyword. But the terms on the "def" line are parameter names that you choose. Avoiding keywords or common function names can prevent errors that can be hard to track down.

10,080 PointsAfter some serious "rubber ducking," here's what passed that challenge: def new(self, int): return int * 2 After some experimentation I found that int * 2 passed the third echelon of this code challenge! Seriously, thank you :)

231,059 PointsCongratulations! But in future you might also want to avoid using a special keyword (like "int") as a variable name.
