dictionary - How to use columns of a key in a dict in Python? -


I dict = { 'a': array [5, 5]} , where Array [5, 5] means that it is read from data file as 5X5 as an array. And I just want to use the first column of value like dict ['a']: array [, 1]] , how can I create it? Thanks! A part of my code: 

  Sync [C% i '% i] = np.loadtxt (' 0cracknodecoord.txt ', usecols = (0, 1)) print (coordination [ 'C1': array [:, [1]]]

print (coordination [ 'C1': array [:, [1]]]) did not work.

I'm not sure, but I think you want: 

  dict [ 'a'] [:, 1]

you were very close before!

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.
