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।
