Why python sdk of mqtt needs pem file, while java sdk not? [message #1755288]

python mqtt client with tls:
tls_set(ca_certs, certfile=None, keyfile=None, cert_reqs=ssl.CERT_REQUIRED,
tls_version=ssl.PROTOCOL_TLSv1, ciphers=None)

it needs "ca_certs" which is a pem file.

java mqtt client with tls:
MqttClient mqttClient = new MqttClient("ssl://xxxx:8884", clientId);

No pem file is necessary.

Why?
Can I use python tls mqtt without pem file?

Python under the covers uses OpenSSL (written in C), which uses different configuration files for TLS/SSL to Java.

Is it possible to use any "default" root certificate in C/C++/Python as it does in Java?
