hi i am begginer in python. I have written a code and given this error: IndexError: list index out of range
In my program, I have h=32 bits input. i divide this 32 bits to 4*8 block and every 8-block is n. so n=0:7;(h=int(n/4)) I want to rotate 0 to 7 bits for 2 bits: 0,1,2,3,4,5,6,7--->2,3,4,5,6,7 Iwrite this code: def rottwo(self, X, n, r): assert r >= 1 temp = [None]*n for i in range(n-r) : temp[i] = X[i+r] for i in range(n-r,n) : temp[i] = X[i-n+r] return temp this function work correctly. but I also want to rotate 24 to 31 bits for 5 bits: 24,25,26,27,28,29,30,31-->29,30,31,24,25,26,27,28 when I write this code: def rotfive(self, X, n, r): assert r >= 1 temp = [None]*n for i in range(n-r) : temp[i+24] = X[i+3*n+r] for i in range(n-r,n) : temp[i+24] = X[i+2*n+r] return temp beacase temp is of size n I cannot access index 3*n+i. index on the list temp should be less than equal to n-1 . I son't know how I must correct this!!!!!!!! Is there any one to help me? thanks in advanse. -- https://mail.python.org/mailman/listinfo/python-list
