Answer 1

from tkinter import Tk, Text, END

root = Tk()
text = Text(root)
text.insert(0.0,
"""This is the first line
This is the Second line
This is the Third line""")
text.pack()
lines = text.get(0.0, END).split("\n") #That's the line you need
print(lines)

root.mainloop()

命令行输出：['This is the first line', 'This is the Second line', 'This is the Third line', '']

它在最后留下一个空白项目，但如果您使用以下内容，您可以将其删除：

lines = text.get(0.0, END).split("\n")[:-1]

这将输出：['This is the first line', 'This is the Second line', 'This is the Third line']
