How to get a list of variables in specific Python module?

Question

Let\'s assume I have the following file structure:

data.py

foo = []
bar = []
abc = \"def\"

core.py

Answer 1

This is the version I wrote for python 3.7 (it excludes the internal dunder methods via the condition in the comprehension)

print([v for v in dir(data) if v[:2] != "__"])

A longer but complete working example is below:

"""an example of a config file whose variables may be accessed externally"""
# Module variables
server_address = "172.217.167.68"
server_port = 8010
server_to_client_port = 8020
client_to_server_port = 8030
client_buffer_length = 4096
server_buffer_length = 2048

def printVariables(variable_names):
    """Renders variables and their values on the terminal."""
    max_name_len = max([len(k) for k in variable_names])
    max_val_len = max([len(str(globals()[k])) for k in variable_names])

    for k in variable_names:
        print(f'  {k:<{max_name_len}}:  {globals()[k]:>{max_val_len}}')

if __name__ == "__main__":
    print(__doc__)
    ks = [k for k in dir() if (k[:2] != "__" and not callable(globals()[k]))]
    printVariables(ks)

The above code outputs:

an example of a config file whose variables may be accessed externally
  client_buffer_length :            4096
  client_to_server_port:            8030
  server_address       :  172.217.167.68
  server_buffer_length :            2048
  server_port          :            8010
  server_to_client_port:            8020
