Nothing. They are local to the function that creates them.

No to both of those. You have two functions, each with it's own locals.
def spam():
colour = "red"
print("Inside spam: colour is:", colour)
eggs()
print("Inside spam after calling eggs: colour is:", colour)
eggs()
def eggs():
colour = "yellow"
print("Inside eggs: colour is:", colour)
Calling spam() gives you this output:
py> spam()
Inside spam: colour is: red
Inside eggs: colour is: yellow
Inside spam after calling eggs: colour is: red
Inside eggs: colour is: yellow
Even if the functions call each other (mutual recursion) each function's
local variables remain local.
