 The script accepts two optional integer arguments, namely --cpp and --cuda.
 By default they are both set to 1.  If you want to exclude CUDA source from
 linting, use:
 
   .. code-black:: bash
     cd /path/to/xgboost/
-    python tests/ci_build/tidy.py --cuda=0
+    python3 tests/ci_build/tidy.py --cuda=0

   .. code-black:: bash
     cd /path/to/xgboost/
-    python tests/ci_build/tidy.py --cpp=0
