Why does VBA not accept the call? ipr101 Try - Call CatSubProduktAreakum(Stattyp, Daty + UBound(SubCategories) + 2) As for the reason, this from MSDN via this question - What does the

问题 What I am trying to do is pretty simple. I want to call the following command using python's subprocess module. cat /path/to/file_A > file_B The command simply works and copies the contents of file_A to file_B in current working directory. However when I try to call this command using the subprocess module in a script it errors out.

Javascript inheritance: call super-constructor or use prototype chain?

阅读更多关于 Javascript inheritance: call super-constructor or use prototype chain?

Quite recently I read about JavaScript call usage in MDC https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/call one linke of the example shown below, I still don't understand. Why are they using inheritance here like this Prod_dept.prototype = new Product(); is this necessary? Because there is a call to the super-constructor in Prod_dept() anyway, like this Product.call is this just out of common behaviour? When is it better to use call for the super-constructor or use the prototype chain? function Product(name, value){ this.name = name; if(value >= 1000) this.value

Explanation of [].slice.call in javascript?

阅读更多关于 Explanation of [].slice.call in javascript?

I stumbled onto this neat shortcut for converting a DOM NodeList into a regular array, but I must admit, I don't completely understand how it works: [].slice.call(document.querySelectorAll('a'), 0) So it starts with an empty array [] , then slice is used to convert the result of call to a new array yeah? The bit I don't understand is the call . How does that convert document.querySelectorAll('a') from a NodeList to a regular array? What's happening here is that you call slice() as if it was a function of NodeList using call() . What slice() does in this case is create an empty array, then

What does it mean to “call” a function in Python? [closed]

What does "call" mean and do? How would you "call" a function in Python? When you "call" a function you are basically just telling the program to execute that function. So if you had a function that added two numbers such as: def add(a,b): return a + b you would call the function like this: add(3,5) which would return 8. You can put any two numbers in the parentheses in this case. You can also call a function like this: answer = add(4,7) Which would set the variable answer equal to 11 in this case. Shashank I'll give a slightly advanced answer. In Python, functions are first-class objects .
