file - close() a variable in Python -


इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 3 जवाब

मेरे पास निम्न कोड है: 

  sys import argv स्क्रिप्ट से, फ़ाइल नाम = argv txt = open (filename) प्रिंट "यहां आपकी फाइल% r है:"% filename print txt.read () print "फ़ाइल नाम फिर से टाइप करें:" फ़ाइल_गेन = कच्चे_इनपुट ("& gt;") txt_again = open (file_again) print txt_again.read ()

और मेरी पुस्तक में से एक में यह कहते हैं, "क्या आपकी स्क्रिप्ट भी बंद करें () पर txt और txt_again वेरिएबल्स। फाइलों को बंद करना महत्वपूर्ण है जब आप उनके साथ कर लें।

मैं चर को कैसे बंद कर सकता हूं?

<सह De> txt.close () फ़ाइल पार्सर को बंद कर देगा। हालांकि मैं इसके बजाय के साथ उपयोग का सुझाव देता हूं: 

  खुले (फ़ाइलनाम) के साथ txt: print "यह आपकी फ़ाइल% r है:"% filename print txt.read () प्रिंट "फ़ाइल नाम फिर से टाइप करें:" file_again = raw_input ("& gt;") को खुले (file_again) के साथ txt_again प्रिंट txt_again.read ()

यह सुनिश्चित करता है कि फ़ाइल पार्सर ठीक से बंद हो गया और क्लीनर अधिक अजगर कोड के लिए भी बना।

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.
