Unable to get the value returned
data=[1,2,3,4,5,6,7,8,10] def event(data): duration=0 def delta(data): first=data last=data duration =last - first print(duration) return duration def division(duration): a=duration/3 print(a) delta(data) print(duration) division(duration) event(data)
The ouput I got is
9 0 0.0
The value 9 is not returned to duration,which was initialized to 0.Hence not able to compute division(duration) correctly
the output that i want is
9 9 3
To "get" the return value of a function, you need to either use it immediately or assign it (bind it to a name). Assignment is what you need here since you use the result twice. It is performed by the
= operator. You could do something like this:
duration = delta(data) print(duration) division(duration)
Keep in mind that the
duration you define in your
delta function has nothing to do with the one in
event because they are in different namespaces. If you want to be able to set
delta, you can let Python know that you want to access something in an enclosing function using
nonlocal. An alternative to having a return value from
delta would be to add the following first line to it:
That being said, this is not the recommended solution. If is much better to keep your namespaces completely separate and just fix your return value assignment.
As a side note, consider redefining
last = data[-1]. Python let's you index from the end of a list using negative indices.
I can't get a return value from Ajax, Returning the result array will only return to the PHP function calling it, instead you actually need to output it by echoing it, and in this case CREATE PROCEDURE <spnamegoeshere> AS BEGIN /* Some code goes here */ return 102323 /*Need to get this value*/ END GO We are executing a Stored Procedure (hosted in SQL SERVER), through JPA using . createStoredProcedureQuery("spnamegoeshere"); I need to get that returned value "102323". Unfortunatly, using above command, unable to get.
You should edit a line with
duration = delta(data) as the return isn't being stored.
I've tested the code and it works with this modification.
Problem is that the description variable inside delta function is not same as the one you defined with
duration= 0. inside a function its a local variable. So, either catch the return to duration or use a duration as a
global variable. One more way is to just put
nonlocal duration in delta function
delta(data) print(duration) division(duration)
duration=delta(data) print(duration) division(duration)

Some Tips, Tricks, and Common Errors, But if the function should return a value, make sure all execution paths do There are only four really important operations on strings, and we'll be able to do A method with a ref return can return an alias to a variable whose value is currently the null (uninstantiated) value or a nullable value type for a value type. The return value cannot be a constant, an enumeration member, the by-value return value from a property, or a method of a class or struct.
