Difference between link and @import

避免@import提升网页加载速度

原文don’t use @import

  • Using @import within a stylesheet adds one more roundtrip to the overall download time of the page.
  • Using @import in IE causes the download order to be altered. This may cause stylesheets to take longer to download, which hinders progress rendering making the page feel slower.

翻译:

  • 在样式表中使用@import增加一个甚至更多来回的页面整体下载时间 

 

  • 在IE中使用@import导致下载顺序乱序,这个可能会导致样式表花更多时间来下载, 导致渲染进程感觉渲染很慢。

Description You are provided with a stub where you must insert your code without modifying the existing structure to complete the task. You may import any pre-installed module in Ed if needed. The current code generates a random list of integers between 2 and 10 whose length is chosen by the user and displays the list. Your task is to output • the square difference between the first and the last values of the list, • the values as horizontal bars of at signs (@), and • the integer half of the values as vertical bars of hash symbols (#). Marking Square Difference 1.0 mark Horizontal Bars 1.5 marks Vertical Bars 1.5 marks -------------------------------------------- Total 4.0 marks Due Date and Submission Quiz 1 is due Week 3 Thursday 19 June 2025 @ 9.00pm (Sydney time). Note that late submission with 5% penalty per day is allowed up to 3 days from the due date, that is, any late submission after Week 3 Sunday 22 June 2025 @ 9pm will be discarded. Make sure not to change the filename quiz_1.py while submitting by clicking on [Mark] button in Ed. It is your responsibility to check that your submission did go through properly using Submissions link in Ed otherwise your mark will be zero for Quiz 1. 1 Test Cases $ python quiz_1.py Enter two integers, the second one being strictly positive: 3 1 Here are the generated values: [5] The square difference between the first and the last values is: 0 Here are the values represented as horizontal bars: @ @ @ @ @ Here are the integer half of the values represented as vertical bars: # # $ python quiz_1.py Enter two integers, the second one being strictly positive: 7 2 Here are the generated values: [7, 4] The square difference between the first and the last values is: 9 Here are the values represented as horizontal bars: @ @ @ @ @ @ @ @ @ @ @ Here are the integer half of the values represented as vertical bars: # # # # # 2 $ python quiz_1.py Enter two integers, the second one being strictly positive: 4 3 Here are the generated values: [5, 6, 3] The square difference between the first and the last values is: 4 Here are the values represented as horizontal bars: @ @ @ @ @ @ @ @ @ @ @ @ @ @ Here are the integer half of the values represented as vertical bars: # # # # # # $ python quiz_1.py Enter two integers, the second one being strictly positive: 0 8 Here are the generated values: [8, 8, 2, 6, 10, 9, 8, 6] The square difference between the first and the last values is: 4 Here are the values represented as horizontal bars: @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ Here are the integer half of the values represented as vertical bars: # # # # # # # # # # # # # # # # # # # # # # # # # # # # 3 $ python quiz_1.py Enter two integers, the second one being strictly positive: 2 15 Here are the generated values: [2, 3, 3, 7, 4, 6, 6, 5, 2, 4, 8, 8, 10, 7, 10] The square difference between the first and the last values is: 64 Here are the values represented as horizontal bars: @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ Here are the integer half of the values represented as vertical bars: # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #
