The built-in assignment operators return the value of the object specified by the left operand after the assignment (and the arithmetic/logical operation in the case of compound assignment operators). The resultant type is the type of the left operand. The result of an assignment expression is always an l-value.
How It Works: Function with a Return Value: A function calculates a result or performs an operation and returns the output using the return statement. Pass the Return Value: Another function can use this returned value as an argument or input for further operations.
Print is for people. Save it for later. The returned value may be: Assigned to a variable. Use it in a more complex expression. In that case, think of the return value as replacing the entire text of the function invocation. Print it for human consumption. For example, print(square(3)) outputs 9 to the output area.
Python allows for returning a function from within another function. This enables dynamic programming patterns. def outer_function(): def inner_function(): return "Hello from the inner function!" return inner_function func = outer_function() print(func()) # Outputs: "Hello from the inner function!"
To return a value from a function, you must include a return statement, followed by the value to be returned, before the function's end statement. If you do not include a return statement or if you do not specify a value after the keyword return, the value returned by the function is unpredictable.
Use the IF function, one of the logical functions, to return one value if a condition is true and another value if it's false. For example: =IF(A2>B2,"Over Budget","OK") =IF(A2=B2,B4-A4,"")
