如何使用 python 将文本附加到文件？

Question

我正在尝试创建一个可以连续添加“../”的文件。我的代码如下：

with open("/tmp/newfile.txt", "a+") as myfile:
  myfile.write('../')
  contents = myfile.read()
  print(contents)

然而，当我运行这个代码时returns<empty>

追加文件：

with open("newfile.txt", "a+") as file:
    file.write("I am adding in more lines\n")
    file.write("And more…")

读取文件：

with open('newfile.txt') as f:
    lines = f.readlines()
     print(lines)

How do I append text to a file with python?
