首先写作一篇自我介绍的英文文章，然后编写程序，先追加一行姓名、学号到原有文件，然后读取文档中的全部内容，并打印输出。效果如图所示。 注意：文件打开模式的选择，文件及时关闭，可以按行读取文件内容。

Here is my self-introduction:

My name is Tom, and I am a junior student majoring in computer science. I have a strong passion for programming and enjoy exploring new technologies. In my spare time, I like to participate in programming contests and contribute to open-source projects. I believe that continuous learning is the key to success in this rapidly changing field, and I am always eager to learn more.

And here is the program that appends my name and student ID to the original file and prints out the entire content:

# Open the file in append mode and write my name and student ID
with open("self_introduction.txt", mode="a") as f:
    f.write("\nName: Tom\nStudent ID: 123456")

# Read and print the entire content of the file
with open("self_introduction.txt", mode="r") as f:
    content = f.readlines()
    for line in content:
        print(line.strip())

The output will be:
