1.从新获取源代码.xlsx的文件，用spider.ipynb文件来修改关键词运行失败，不能运行但是没有报错的红点，猜测是数据包的问题，开始搜索下载数据包的方法
用pip install 在终端页面中将缺少的包下载好
2.在运行到第三框的时候出现了报错，在这里的解决方案是直接自己扫码登录
值，那么原始变量的值不会受到影响。这种传递方式在Java中也被称为"按值传递"。
特点为：
方法调用结束后，基本数据类型的参数变量值不会改变，因为修改的只是其值的拷贝，而不是变量本身。
2.引用数据类型传递
引用数据类型包括类、接口、数组等类型。当引用数据类型作为参数传递给方法时，实际上传递的是对象的引用（也就是内存地址）的拷贝。这意味着，如果在方法内部通过这个引用改变了对象的状态（即修改了对

1. When attempting to run the keyword-modified script using the newly acquired `Source Code.xlsx` file via the `spider.ipynb` notebook, the script failed to execute without displaying any error red dots. It was inferred that the issue stemmed from missing packages, so we began searching for ways to download the required packages. We installed the missing packages using `pip install` in the terminal.
2. An error occurred when running the third code cell. The solution at this point is to directly scan a QR code to log in.

The value of the original variable will not be affected. This passing mechanism is also referred to as "pass-by-value" in Java. Its characteristics are as follows: After the method call completes, the value of the primitive data type parameter variable remains unchanged, as only a copy of its value is modified rather than the variable itself.
2. Passing of reference data types
Reference data types include classes, interfaces, arrays and other types. When a reference data type is passed as a parameter to a method, what is actually passed is a copy of the object's reference (i.e., memory address). This implies that if the state of the object is altered via this reference within the method (i.e., modifying the
