帮我翻译以下代码import re def gettitle(name): title=re.search(' ([A-Za-z]+)\.',name) if title: return title.group(1) else: return '' full_data['Title']=None for i in range(len(full_data)): full_data['Title'][i]=gettitle(full_data['Name'][i])

这段代码的功能是从一个包含姓名信息的数据集中提取出人名中的称号,并将其存储到数据集的“Title”列中。具体实现方法是使用Python中的re模块(即正则表达式模块),通过正则表达式搜索匹配人名中的称号。如果找到了称号,则将其存储到“Title”列中;否则将“Title”列设置为空字符串。
这段代码中的gettitle函数接受一个名字作为参数,使用正则表达式从中提取出称号。具体来说,它使用re.search函数来查找名字中的“ [A-Za-z]+\\.” 字符串,其中“[A-Za-z]+”匹配任意连续的字母,而“\\.”匹配点号。如果查找成功,则返回匹配到的第一个分组(也就是称号);否则返回空字符串。
接下来的for循环遍历数据集中的每一行,对于每一行的“Name”列,调用gettitle函数来提取出称号,并将其存储到“Title”列中。最终,数据集的“Title”列将包含所有人名中的称号信息。

帮我写以下代码:The problem with the MajorRequired class above is that the constructor takes a MajorRequired object as the third argument and it cannot be null. This means that, to create a major required course, you need to already have another major required course. In turn this means that you cannot create any major required course at all, because you cannot create the first one! To solve this problem, add to your program a Base class with the following UML specification: +-----------------------------------+ | Base | +-----------------------------------+ | - code: String | | - title: String | +-----------------------------------+ | + Base(String code, String title) | | + getCode(): String | | + getTitle(): String | | + getPreRequisite(): Base | | + testBase(): void | +-----------------------------------+ Base courses do not necessarily have any pre-requisite, so the getPreRequisite method will return itself. Your Base class should also contain a static method called testBase() that contains the unit tests of Base class. Do not forget to change the main method of the Start class to run the unit tests of the new Base class.
以下是你需要的Java代码:
public class Base {
private String code;
private String title;
private Base preRequisite;
public Base(String code, String title) {
this.code = code;
this.title = title;
this.preRequisite = this;
}
public String getCode() {
return code;
}
public String getTitle() {
return title;
}
public Base getPreRequisite() {
return preRequisite;
}
public static void testBase() {
Base test = new Base("CS101", "Introduction to Computer Science");
if (!test.getCode().equals("CS101")) {
System.out.println("getCode() method error");
}
if (!test.getTitle().equals("Introduction to Computer Science")) {
System.out.println("getTitle() method error");
}
if (test.getPreRequisite() != test) {
System.out.println("getPreRequisite() method error");
}
}
}
public class MajorRequired {
private String code;
private String title;
private Base preRequisite;
public MajorRequired(String code, String title, Base preRequisite) {
this.code = code;
this.title = title;
this.preRequisite = preRequisite;
}
public String getCode() {
return code;
}
public String getTitle() {
return title;
}
public Base getPreRequisite() {
return preRequisite;
}
public static void main(String[] args) {
Base.testBase();
}
}
注意:当你使用该代码时,请确保正确设置了类路径和包路径,包路径可能需要根据你的IDE或编译器进行修改,并确保文件名和类名匹配。
代号代码= Part.Extension.CustomPropertyManager("").Set("代号",Left(Part.GetTitle,InStr(Part.GetTitle," "))) 名称代码= Part.Extension.CustomPropertyManager("").Set("名称", Left( Right(Part.GetTitle,Len(Part.GetTitle)-InStr(Part.GetTitle," ") ) ,Len( Right(Part.GetTitle,Len(Part.GetTitle)-InStr(Part.GetTitle," ") ) ) -7 ) )是什么意思
这是一段 SolidWorks API 程序代码,用于设置 SolidWorks 零件的自定义属性。
第一行代码:
代号代码= Part.Extension.CustomPropertyManager("").Set("代号",Left(Part.GetTitle,InStr(Part.GetTitle," ")))
意思是,使用 SolidWorks API 函数 Part.Extension.CustomPropertyManager() 创建一个自定义属性管理器,然后使用 Set() 方法设置一个名为“代号”的自定义属性,并将它的值设置为 SolidWorks 零件的标题的左边部分(即截取零件标题的第一个空格前的部分)。
第二行代码:
名称代码= Part.Extension.CustomPropertyManager("").Set("名称", Left( Right(Part.GetTitle,Len(Part.GetTitle)-InStr(Part.GetTitle," ") ) ,Len( Right(Part.GetTitle,Len(Part.GetTitle)-InStr(Part.GetTitle," ") ) ) -7 ) )
意思是,使用 SolidWorks API 函数 Part.Extension.CustomPropertyManager() 创建一个自定义属性管理器,然后使用 Set() 方法设置一个名为“名称”的自定义属性,并将它的值设置为 SolidWorks 零件的标题的右边部分(即截取零件标题的第一个空格后的部分,再去掉最后的 7 个字符)。
简而言之,这两行代码的作用是,从 SolidWorks 零件的标题中提取出两个自定义属性,分别命名为“代号”和“名称”,并将它们的值设置为标题的两部分。
