Get OS pretty name using Python, Raspberry Pi OS

Python 3 exercise run on Raspberry Pi 5 running 64-bit Raspberry Pi OS (bookworm) to read OS pretty name (such as Debian GNU/Linux 12 (bookworm)) by reading and parsing the file "/etc/os-release".

pretty_name.py

with open("/etc/os-release") as f:
    os_release = {}
    for line in f:
        k,v = line.rstrip().split("=")
        os_release[k] = v.strip('"')

for keys, values in os_release.items():
    print(keys, ":", values)

print()
pretty_name = os_release['PRETTY_NAME']
print("PRETTY_NAME:", pretty_name)

Output:
