Comma

Hi, ..


The following I came across online and is talking about virtual environments in Python (a programming language):

"Different applications can then use different virtual environments. To resolve the earlier example of conflicting requirements, application A can have its own virtual environment with version 1.0 installed while application B has another virtual environment with version 2.0. If application B requires a library be upgraded to version 3.0, this will not affect application A’s environment."


My question is, shouldn't there go a comma before while?

".. with version 1.0 installed, while application B"


Thanks in advance.

  • Without the comma, the reader expects it to mean "during the time that".

Yes. "While" is a coordinating conjunction there meaning "and on the contrary". Without the comma, the reader expects it to mean "during the time that".

The comma is not mandatory. Some people might include it for readability, while others might not bother.
