Explanation

If you run this code to decorator a new function, you will get name error, regardless the colon in line 3 is missing or not. NameError: name 'level2_warpper' is not defined. This is because our_function (line 4) and my_function(line 2) did not return the SAME function line 2: def level1_wrapper(my_function) line 4: return our_function To make this code correct, you can make FUNCTION_NAME in line 2 and line 4 consistency. eg. line 4 should be 'return my_function'.
