Why does my Python class claim that I have 2 arguments instead of 1? -

  #! / Usr / bin / env python आयात os आयात स्टेट आयात सीएस वर्ग chkup: def सेट (फ़ाइल): filepermission = os.stat (फ़ाइल) user_read () user_write () user_exec () def user_read (): "" 'फ़ाइल' उपयोगकर्ता द्वारा पठनीय है "# फ़ाइल की (या # निर्देशिका के) स्टेट जानकारी से अनुमतियाँ बिट्स निकालें। B = bool (filepermission.st_mode & amp; stat.S_IRUSR) प्रिंट रिटर्न बी डीईएफ़ user_write (): "" रिटर्न ट्रू यदि 'फाइल' उपयोगकर्ता द्वारा पठनीय है # "फ़ाइल की अनुमतियाँ बिट्स निकालें (या # निर्देशिका की ) स्टेट जानकारी B = bool (filepermission.st_mode & amp; stat.S_WRUSR) प्रिंट रिटर्न बी डीईआर user_exec (): "" रिटर्न ट्रू यदि 'फाइल' उपयोगकर्ता द्वारा पठनीय है # "फ़ाइल की अनुमतियाँ बिट्स निकालें (या # निर्देशिका ) स्टेट जानकारी B = bool (filepermission.st_mode और stat.S_IXUSR) प्रिंट बी रिटर्न बी डीईफ़ मुख्य (): i = chkup () स्थान = '/ नेट / होम / एफटी 8 / आईटीआर 1 / स्क्रिप्टिंगवर्क / कोटैशैक' i.set (स्थान) अगर __name__ == '__main__': मुख्य ()

उस कोड के साथ मुझे प्राप्त होता है 

  & gt; ट्रेसबैक (सबसे हाल की कॉल अंतिम): फ़ाइल "chkup.py", पंक्ति 46, & lt; मॉड्यूल & gt; मुख्य () फ़ाइल "chkup.py", रेखा 43, मुख्य आई.सेट (स्थान) में प्रकार: त्रुटि: सेट () बिल्कुल 1 तर्क (2 दिया) लेता है

कोई भी विचार?

अजगर वर्ग विधि के लिए पहला तर्क self चर है यदि आप classInstance.method (पैरामीटर) को कॉल करते हैं, तो विधि को विधि (आत्म, पैरामीटर) के रूप में लागू किया जाता है ।

इसलिए, जब आप परिभाषित कर रहे हैं

आप पढ़ सकते हैं के माध्यम से।

Just want to know how I will create UIPickerView in a UIActionSheet with a simple array. Well, I really know how to put it in an action sheet but I like my way because it is more for my app, thanks, but I I also want to know how to put options in UIPKviewView, I just have an array with colors already on top of that part: red, green, blue, yellow, black, etc. in this, but I want to know how it In the preview d L'be if I am using the already Instifrem:? Please help anyone. I know that this is a stupid question, but I'm cheating my head on my $$$$$$ MacBook. Instead you want to do this, create your UIPickerView interface builder and have it in your view controller Connect to the outlet. Add it as a subview of your main view and set its frame coordinates so that it is offset right below the edge, x = 0, y = 480 Then, when you want to display a picker, animate it like something with the screen: [UIView startup permissions: zero reference: zero]; [Color picture setfr...

excel - Populate list via a bi-Condition -

I'm interested in implementing something but I'm not sure it would be possible and would like to take it on. This is my scenario: I will have two verification cells, which will be shown as a list, from which I will select. This is my condition that I want to remember and remember my list from a database. I have a list of agents, which has been thrown at B13: B23 and the next two, I have columns of data that assume that my data base looks like this bcdx | Y Z Agent 1 1 | 1 | 0 Agent 2 0 | 1 | 0 Agent 3 0 | 1 | 1 agent 4 1 | 0 | 0 ... I want to populate a list named agent from column B, when I verify cell 1: x and verification cell 2: 1 I choose from. It should only show an agent in column X with column: agent1 agent4 or 0 ... I read somewhere Array formula but I do not know if this is convenient and I have unfortunately not any background in the macro :( But I know C ++ is quite easy with some conditional statement like this. Advance Thanks, This...
