Join strings with a separator.
Combine a list of strings into one readable string with a separator between each item.
languages = ["Python", "Bash", "SQL"]
result = ", ".join(languages)
print(result)Expected output EXAMPLE
Python, Bash, SQL
Details
Uses only the Python standard library; no pip packages are required. See the verification record below for the exact Python version tested.
Every item must be a string. For numbers, use ", ".join(map(str, numbers)).
Tested on Ubuntu 24.04.5 LTS · · Python 3.12.3 · python3 3.12.3-0ubuntu2.1
Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Unprivileged snippet process, external networking disabled, read-only root filesystem, and a fresh temporary working directory. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
