Python Lambda in a loop [duplicate]

Answer 1

I met the same problem. The selected solution helped me a lot, but I consider necessary to add a precision to make functional the code of the question: define the lambda function outside of the loop. By the way, default value is not necessary.

foo = lambda d: lambda : self.root.change_directory(d)
for d in directorys:
    self.command["cd " + d] = (foo(d))
