In the course of converting some variables from an API, I need to check if the API is returning a string, such as " N/A", and not a number such as "824". This is the code that I'm attempting to use where, if the variable from the API is a number, leave it alone, otherwise, change it to a = (Zero)
$weather["barometer_min"] = (is_numeric($weewxapi[36]) ? number_format($weewxapi[36],0) : "0");
It does not appear to be working, however, it is not throwing any errors. Can anyone guide me in the right direction?
As shown by Syscall, using 3v4l.org, the code works.

I am newbie in pyspark. In the following ways of the writing the code:
1st way:
s_df= s_df.withColumn('sum', s_df['Col1'] + s_df['Col2'] )
s_df= s_df.withColumn('difference', s_df['Col1'] - s_df['Col2'] )
2nd way:
s_df= ( s_df.withColumn('sum', s_df['Col1'] + s_df['Col2'])
.withColumn('difference', s_df['Col1'] - s_df['Col2']) )
It is always advisable to use the second one, this has to do something with how spark works internally. Can anyone please give me a detailed reason for this?
There is no difference between those 2 "ways" as you describe it, as #mck points out, s_df.explain() will be the same for both cases.
I don't think there is an official or "advisable" way to write code, as Spark doesn't provide any style guidelines in its document. However, I find it's easier writing it this way (more readable and maintainable)
s_df = (s_df
.withColumn('sum', s_df['Col1'] + s_df['Col2'])
.withColumn('difference', s_df['Col1'] - s_df['Col2'])
)
Also, it's worth mentioning that even though it's totally legitimate to override s_df, but you will lost your original dataframe which you probably will need it later.

I want this result:
I have a state JSONModel contains the states that I want bind with my UI.
{
code:"None",
descr:"Error"
family:"None"
}
Now, to have my result, I write:
sap.ui.getCore().byId("idCodeInput").setValueState("{state>code}");
sap.ui.getCore().byId("idDescrInput").setValueState("{state>descr}");
sap.ui.getCore().byId("idFamilyInput").setValueState("{state>family}");
and it works fine.
But sap.m.Input doesn't not have valueState property and I can't bind model<-->view from the XML of view. I would like write some like this:
<Input
valueState ="{state>descr}"
value="{model>descr}"
enabled="{enable>descr}"
/>
sap.m.Input has a property valueState

The main aspect of CoffeeScript I'd like to see available also for Dart in form of a different, Dart-based language would be less verbosity, less brackets, less Java-style.
Does such solution exist ?
No.
If you don't want to have your field static you can omit the static keyword.
If you don't want to have your field final you can write var or a concrete type instead of the final keyword.
And if you don't want a loop you can omit for, while, forEach, ...

I keep getting this error from this line of code:
result = simplify_path(obj.path_(mlength -2), obj.path_(mlength-1), obj.path(mlength));
result is just a temp variable and the everything has already been defined and works at other places in the code.
simplify_path is a function I defined elsewhere in another file. It is NOT method of my class. I made sure that everything is spelled correctly.
What is going on?
try:
result = simplify_path(obj.path_(mlength -2), ...
obj.path_(mlength-1),...
obj.path_(mlength));

Is there any way that I can list all called methods like there are called one after the other? For example now I am doing same thing in way that I'm putting NSLog(#"MethodName"); i every that method.
I want to do that by automatic way in NSLog. Is it possible?
If you don't have too much methods you can use
NSLog(#"%#" , NSStringFromSelector(_cmd));
to log their names. This way you don't have to copy the signatures manually each time.
Create a property 'NSMutableArray *calledMethods;`
And in each of your method use
[self.calledMethods addObject:NSStringFromSelector(_cmd)];
And whenever you want to print it NSLog it.
I think you want:
printf("%s\n", __PRETTY_FUNCTION__ ) ;
Which produces (for example)
-[AppDelegate application:didFinishLaunchingWithOptions:]
Or, you can use dtrace. This answer should help: https://stackoverflow.com/a/3874726/210171.
Also check https://stackoverflow.com/a/4604249/210171 (same linked question). Seems there's an environment variable NSObjCMessageLoggingEnabled you can set...
