Is there a significant difference in assigning values one-by-one and with tuples in Python? -


Whether there is a big difference in the time, memory usage, or two statements in some: 

  (Script_name, option1, option2) = (sys.argv [0], sys.argv [1], sys.argv [2])

and

< Pre> script_name = sys.argv [0] option1 = sys.argv [1] option2 = sys.argv [2]

(no value optparse is used)

No significant differences Thanks to Bettecode Payfool Optimization, in the first one Not even a temporary Tupal construction Is. Even if there is, dirt is cheap in making and deleting tuples.

Personally, I write it as 

  script_name, option1, option2, * _ = sys. Argv # or script_name, option1, option2 = sys.argv [: 3]

I think it raises a different, perhaps more deceptive error message, if there are very few command line logic , But an good error message requires a clear check in advance, I have no problem.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
