+```python
+import pysnooper.snoop

+# use my_snoop to debug. my_snoop will always be enabled, stderr will redirect output to a file
+my_snoop = snoop.setup(output='/my/log/file.log', disable=False)
+
+@my_snoop()

+    y = 10
+    return x + y
+```
+Notice that `PYSNOOPER_DISABLED` will be invalid if `disable` parameter is specified in `setup()`
