Permutation of first few integers in Python -


I want to go through all the permutations of Python (1,2,3,4,5) For some sort of calculation, such as 

  in the permutation lists for li: # Calculation list = [[1,2,3,4,5], [1,2,3,5] , 4], ...] Print Lei [0] - L [1] + Lee [2] -li [3] + Lee [4]

Through all these passages What would be a convenient way to iterate (As Ashwin Choudhary said in the comment: <2,3,4,5)?

/ P> 

  permutes = permutations of parameters to import ([1, 2,3,4,5]) permits in li: # do stuff

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
