defcube(x):return(x*x*x)print(cube(5)) which will yield: 125 Now what if we desired a function that computed both squares and cubes and returned them both? How can we do that? A Python function can only return one object, not two. The solution is to package the square and cube ...
Python def get_and_save_middle(data, fname): middle = data[len(data)//3:2*len(data)//3] save_to_file(middle, fname) return middle This function saves and returns the middle third of a string. You don’t need to finish implementing save_to_file() before you can test the outp...
In this example, thereturnstatement is incorrectly placed outside the function definition, leading to the error. Method 1: Correcting Indentation One of the most common causes of the “return outside function” error is improper indentation. Python relies heavily on indentation to define the structu...

Add Unit Tests:Create tests that specifically check the function's return type under various input conditions. (See the function example in the "Common Scenarios" section for code demonstrating this problem). Debugging and Tracing:If you're unsure where the integer value is coming from: ...
A unary mathematical expression consists of only one component or element, and in Python the plus and minus signs can be used as a single element paired with a value to return the value’s identity (+), or change the sign of the value (-). ...
In this case, you can let Django take care of all the auto-escaping handling for you. All you need to do is set the is_safe flag to True when you register your filter function, like so: @register.filter(is_safe=True) def myfilter(value): return value This flag tells Django that...
