Python: shuffle and create a new array -


i want shuffle array, find method random.shuffle(x), best way randomize list of strings in python

can like

import random rectangle = [(0,0),(0,1),(1,1),(1,0)] # want # disorderd_rectangle = rectangle.shuffle

now can away with

disorderd_rectangle = rectangle random.shuffle(disorderd_rectangle) print(disorderd_rectangle) print(rectangle)

but returns 

[(1, 1), (1, 0), (0, 1), (0, 0)] [(1, 1), (1, 0), (0, 1), (0, 0)]

so original array changed. how can create shuffled array without changing original one?

people here advising deepcopy, surely overkill. don't mind objects in list being same, want shuffle order. that, list provides shallow copying directly.

rectangle2 = rectangle.copy() random.shuffle(rectangle2)

about misconception: please read http://nedbatchelder.com/text/names.html#no_copies

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
