I’m curious about the difference between lambda function and a regular function (defined with def) – in the python level. (I know what is the difference for programmers and when to use each one.)
I am running Eclipse SDK v3.6 with PyDev v2.6 plugin on two PC, with Linux and Windows. I would like to pass a tuple as an argument, like: foo = lambda (x,y): (y,x) print (foo((1,2))) This works on Linux and gives the correct result: > (2,1) On Windows it rises an error: foo = lambda … Read more
