What is the difference between a communist then a communist government?

A communist refers to an individual who advocates for or supports the ideology of communism, which seeks to establish a classless society where the means of production are collectively owned. In contrast, a communist government is a political system that implements these ideals, often characterized by state control over resources and a single-party rule that promotes communist principles. While individual communists may have diverse views and approaches, a communist government enforces specific policies and structures to achieve its goals.
