the complex, very good understanding. Codecademy the exercises above are not according to the project, a bit like a module, but our goal is to use Python to support data analysis work, not as a Python programmer.The basic step must be the code, one step at a pace, or a indentation will be able to dry people down.Objective to find the average grade of a class and the corresponding result type.#字典的定义方式Lloyd = { "name":"Lloyd", "Homework": [90.0,9

In order to learn programming, many people bought a bunch of related books, and participated in a lot of online courses, and even spent hundreds of yuan to buy a set of teaching CD-ROM, in the end will not be programmed, very worthless. Codecademy is a newly launched web site that provides users with a new way to learn about programming. It is a web-based interactive programming tutorial that helps users understand some of the basics of JavaScript an

In ASP. net mvc, @ Html. Partial, @ Html. Action, @ Html. RenderPartial, @ Html. RenderAction, 1. View of the Action and RenderAction loading method, perform the order of Controller → Model → View, and then bring the generated page back to the original View before returning it. While Partial and RenderPartial directly

1. the return value of the render method is void, which is output within the method. The return value type without the render is mvchtmlstring. Therefore, you can only use the following method: @ Html. Partial @ {html. renderpartial (...) ;}@ html. action @ {html. renderaction (....);} 2.

In ASP. @html.partial, @Html. Action, @Html. renderpartial, @Html. Renderaction differencesMake a summary of these four differences, clean up the idea, convenient for later use:1. The return value of the method with render is void, output inside the method, and the return value type is mvchtmlstring, so this can only be used:@

renderaction are often used to display a relatively independent "block", such as a menu or a navigation bar. The results of both outputs are displayed as part of the view that is called.Different points of the two Renderpatial's data comes from the calling view, and renderpatial comes from itself.

1. The return value of the method with render is void, output inside the method, and without the return value type mvchtmlstring, so use:@Html. Partial corresponds to @{html.renderpartial (...);}@Html. Action corresponds to @{html.renderaction (...);}2, Action, renderaction loading method of the view, the execution of Controller→model→view order, and then the resulting page back to the original view and the

1. The return value of the method with render is void, output inside the method, and the return value type is mvchtmlstring, so this can only be used:@Html. Partial corresponds to @{html.renderpartial (...);}@Html. Action corresponds to @{html.renderaction (...);}2, html.partial can directly provide the user control name as a parameter, and html.action need to have a corresponding action, within the action
