What is the quickest way of doing this?\nI am aware of the numpy.array_equal function (https://docs.scipy.org/doc/numpy-1.10.0/reference/generated/numpy.array_equal.html), however as far as I am aware this only applies to two arrays and I want to check N arrays against each other.\nI also found this answer to test all elements in a list: check if all elements in a list are identical. However, when I try each method in the accepted answer I get an exception (ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all())\nThanks,\nA:\n<code>\nimport numpy as np\na = [np.array([1,2,3]),np.array([1,2,3]),np.array([1,2,3])]\n</code>\nresult = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n\n## What to do\n- Edit `solution/solution.py` so the code passes the DS-1000 tests.\n- Do not access the internet or install new packages; required libraries are preinstalled in the Docker image.\n- Run tests locally via `bash tests/test.sh`.\n\n## Notes\n- Keep the variable names/signatures implied by the prompt/code_context.\n- The evaluator uses the original DS-1000 `code_context` (`test_execution` / `test_string`).\n", "memory": "", "runnable": false, "difficulty": "", "language": "", "cpus": "", "instruction_truncated": false, "category": "", "compose": false, "has_solution": true, "oracle": null, "docker_image": "ds1000:latest", "taskset": "ds1000", "tags": []}, "runs": []}
