msg = "文件【%s】的内容如下:" % title

text_after = g.textbox(msg, title, text)
if text != text_after[:-1]:
# textbox 的返回值会追加一个换行符
choice = g.buttonbox("检测到文件内容发生改变,请选择以下操作:", "警告", ("覆盖保存", "放弃保存", "另存为..."))
if choice == "覆盖保存":
with open(file_path, "w") as old_file:
old_file.write(text_after[:-1])
if choice == "放弃保存":
pass
if choice == "另存为...":
another_path = g.filesavebox(default=".txt")
if os.path.splitext(another_path)[1] != '.txt':
another_path += '.txt'
with open(another_path, "w") as new_file:
new_file.write(text_after[:-1])
text != text_after[:-1],这个[:-1]是啥意思
另存为那个选项的if能帮忙解释一下吗
感谢!! |
