Difference between 看作 and 看成?

Question

Recently， I've been listening to a chinese podcast and in the podcast I heard someone say "中国人常常把谦虚看作一种美德“。 I have also heard the term “叫作” within the podcast - I'm wondering, is there a clear difference between this and 看成／ 教程？

Answer 1

You are right. They are the synonyms. 看作/看成。

The other a pair of synonyms should be 叫作/叫成(instead of 教程.)

Answer 2

看作 and 看成 are interchangeable in the sentence you provided.
