User directory in PATH in zsh: ~ Does Not Work

Question

I am trying to make a basic drawing program with a RadioButton to determine shape of the brush.

self.choseo = Radiobutton(text='Circle', variable=shape,indicatoron=0, value=1)
self.choser = Radiobutton(text='Rectangle', variable=shape,indicatoron=0, value=2)
self.chosea = Radiobutton(text='Arc', variable=shape,indicatoron=0, value=3)

Which corresponds to:

   if shape.get()==3:
      self.display.create_arc( self.x1, self.y1, self.x2,
          self.y2, fill = mycolor, outline= mycolor, tags = "line")
   elif shape.get()==2:
      self.display.create_rectangle( self.x1, self.y1, self.x2,
          self.y2, fill = mycolor, outline= mycolor, tags = "line")
   elif shape.get()==1:
      self.display.create_oval( self.x1, self.y1, self.x2,
          self.y2, fill = mycolor, outline= mycolor, tags = "line")

When i run this i get this error:

"TypeError: get() takes exactly 1 argument (0 given)"

How do i make this work?

Solution

Use $HOME instead.

PATH="$HOME/scripts:$PATH"

What is shape? Generally .get() accepts an index.

Expansion of ~ in PATH is an abhorrent bashism. The PATH-searching library functions execlp or execvp do not expand ~, so other programs that use them to find and run programs in the PATH would also fail to search ~ entries.

I consider ~ to be a command-line convenience. It shouldn't be used in scripts and variable values for expansion.

@Chris Johnsen, it's amazing, the main impact on my *nix knowledge after switching shells is learning what is universal and what is not. I think zsh is cool, but I've learned quite a bit suffering through the switch (and I'm only two days in). @Dennis Williamson, I'm getting that, and it makes sense, somehow.
