问题描述
我在完成任务时陷入困境，我希望获得一些帮助，使我可以使其按预期的方式工作。
任务是程序是一个多项选择测验，需要随机选择一个问题，以随机顺序显示答案，并使用列表使其正常运行。我的问题是我根本无法打印问题。我可以从列表中打印出第一行，但格式错误，并且我无法使程序将正确的答案识别为正确的答案。
我了解我目前拥有的代码还没有完成，但是在我陷入困境之前，我已经尽力了。这是我到目前为止的内容：
qList = [
("Who was the first president to hold a press conference on television?","John F. Kennedy","Dwight D. Eisenhower","Richard M. Nixon","Lyndon B. Johnson"),("Which president served the shortest term (dying 32 days after taking the oath of office)?","William Henry Harrison","Chester A. Arthur","William Taft","Zachary Taylor"),("Who was the first president to be born in a hospital?","Jimmy Carter","Gerald Ford","George H. W. Bush","Martin Van Buren"),("Who was the first president to see the Pacific Ocean?","Ullyses S. Grant","Franklin D. Roosevelt","Warren G. Harding","Theodore Roosevelt"),("Which president served two non-consecutive terms?","grover Cleveland","Franklin Pierce","Millard Fillmore",("Who was the first president to be impeached by the House of Representatives?","Andrew Johnson","Bill Clinton","Donald Trump","John Tyler"),("Which president got stuck in the White House bathtub?","William Howard Taft","John Quincy Adams","Teddy Roosevelt","Millard Fillmore"),("Which president never married? (His niece served as the White House hostess in lieu of a First Lady.)","James Buchanan","James Polk","James Madison","James Monroe"),("Who was the first president to speak with astronauts on the moon?","Richard Nixon","Lyndon B. Johnson","Jimmy Carter"),("Who was the only person to serve as Vice-President and President,but elected to neither office?","Herbert Hoover"),]

解决方法
所以我修改了整个代码，瞧！有用！！！看代码，我在那里写了解释：

如果您没有numpy库，则可以转到cmd或bash并键入：
pip install numpy
应该可以。 ：）
