搜索了一些介绍，只是说r+ 是读加写，w+是写加读，我的问题是：以w+为例，这里的“
读”是指啥意思？好像read不出来？

比如用以下代码复制一个txt，复制是成功的，但是print(newfile.read())却是空的：



with open('old.txt', 'r',encoding='utf-8') as file:

    data = file.read()

    print(data)

with open('new.txt', 'w+',encoding='utf-8') as newfile:

    newfile.write(data)

    print(newfile.read())
