python - How to append new data onto a new line -


मेरा कोड इस तरह दिखता है: 

  def storecores (): hs = open (" Hst.txt "," a ") hs.write (name) hs.close ()

इसलिए यदि मैं इसे चलाता हूं और" रयान "दर्ज करूँ तो इसे फिर से चलाएं और" बॉब " फ़ाइल hst.txt जैसा दिखता है 

  रायन बॉब

के बजाय 

  रयान बॉब

मैं इसे कैसे ठीक करूं?

यदि आप एक नई लाइन चाहते हैं, तो आपको एक लिखना होगा स्पष्ट रूप से। सामान्य तरीका यह है: 

  hs.write (name + "\ n")

यह एक बैकस्लैश एस्केप का उपयोग करता है, \ n , जो पायथन स्ट्रिंग लीटरल में एक नए वर्ण को परिवर्तित करता है। यह आपकी स्ट्रिंग, नाम , और उस नए पंक्ति को एक बड़ी स्ट्रिंग में जोड़ता है, जो फ़ाइल को लिखा जाता है।

इसके बजाय एक बहु-लाइन स्ट्रिंग का उपयोग संभव है , जो इस तरह दिखता है: 

  "" "" "

या, आप कॉन्कटाइनेशन के बजाय स्ट्रिंग फ़ॉर्मेटिंग का उपयोग करना चाह सकते हैं: 

  hs.write ("{} \ n" .format (name))

यह सब ट्यूटोरियल के अध्याय में समझाया गया है।

Python, converting png to gif using ImageMagick -

I am using Python 2.7.6, I had a problem converting some PNG files into GIF (an animation To create) os.system ("Convert-dated 1-Digiage background + page" + str (output_dir) + "/*.png -loop 0" + str (output_dir) + "/ Animation GIF") This was the error on which I have Parametre non welde - 1 Enough to go Without error, this is only an estimate, but ... If there is an empty space or quote in output_dir or other special characters, to avoid or quote you Nothing is doing, so your command line will look something like this: Convert - Day 1-digest background + page ~ / My image / *. Png -loop 0 ~ / My Photos / Animation.gif There may be a completely valid argument for sending ~ / my for input, and Pictures / *. PNG is to solve a full bank Additional relative path that converts is ready to deal with additional inputs, but then you have to ~ / My , which is not valid because it has something similar to the input, and some additio...
