Scala - Booleans - & vs &&, | vs || -


मैंने देखा कि Scala Boolean में दोनों और का समर्थन करता है और & amp; & amp; । क्या इन दो ऑपरेटरों के बीच अंतर है? स्कला डॉक्स उन दोनों के लिए सटीक विवरण का उपयोग करते हैं, इसलिए मुझे यकीन नहीं था।

< कोड> & amp; और | सख्त होते हैं जबकि & amp; amp; & amp; amp; & amp; amp;; और || शॉर्ट सर्किट हैं: 

  झूठा & amp; amp; (नया अपवाद ()) = & gt; झूठी झूठी और amp; (नया अपवाद ()) = & gt; पूर्व सच || (नया अपवाद ()) = & gt; सही सच | (नया अपवाद ()) = & gt; पूर्व

और और | के लिए पूर्ण दस्तावेज इस व्यवहार को समझाते हुए एक नोट है:

यह विधि एक और बी दोनों का मूल्यांकन करती है, भले ही परिणाम का मूल्यांकन करने के बाद पहले ही निर्धारित हो।

Python Equivalent for matlab cart2pol and pol2cart -

I would like to use pol2cart and cart2pol for two functions in MATLAB. Is there an equivalent Python Function? Or if we can define work? For example, I tried to use the CeMatePactor function, but it only accepts one argument, I have 2 arguments to cross the polar and REC function. P> I have tried to use this function for cart2pol: def cart2pol (x, y): theta = atan2 (y, x) rho = Sqrt (x ** 2 + y ** 2) returns (theta, ro) thanks
