What are the advantages of .pkl file over .txt or csv file in python

Question

在 Python 中以 .pkl 格式保存文件比以 .txt 或 .csv 格式保存文件有什么优点？

Answer 1

.pkl 可以序列化非常广泛的对象，而不仅仅是文本数据。

Answer 2

Although you only ask about the advantages, I would like to mention the disadvantages first.

Con:

• Csv file is more popular.
• pkl might have security problem. see here

Pro:

1. PKL is faster.

2. PKL can store any binary subject.

   JSON is a text serialization format (it outputs unicode text, although most of the time it is then encoded to utf-8), while pickle is a binary serialization format;
