Check if elements of one list are in elements of other sub-list

I am using Faker library.

from faker import Faker
fake = Faker()

I have a list of sub-lists (2 elements each); a column name to give the dataframe, and the function invocation itself.

A list of all function names, excluding names of functions that start with a "_":

my_list = [[m, 'fake.'+m+'()'] for m in dir(fake) if m[0] != '_']
my_list
>>> [['add_provider', 'fake.add_provider()'],
 ['address', 'fake.address()'], ...

Now, I want to add another condition to the same for loop, excluding function names.

Attempted Solution:

exclude = ['add_provider']
fake_cols = [[m, 'fake.'+m+'()'] for m in dir(fake) if function_name in exclude or function_name[:1] == "_"]
fake_cols

Output is empty:

[]

Any solutions that are more concise would be appreciated.

Maybe a little overhaul would do it, look at the following, if that does what you are aiming for:

import faker

faker = faker.Faker()

exclude = ["add_provider", "address"]
faker_functions ={}
for function_name in dir(faker):
    if function_name in exclude or function_name[:1] == "_":
        continue
    try:
        faker_functions[function_name] =  getattr(faker, function_name)
    except:
        continue

def get_list_of_fake_functions():
    return list(faker_funcktions.keys())

def get_fake(fake_function):
    return faker_functions[fake_function]()

my_list =  [[key, "faker."+ key+ "()"] for key in faker_functions.keys()]
my_list

Error as expected because excluded:

get_fake("zipcode_plus4")
KeyError: 'zipcode_plus4'

or result if not

get_fake("zipcode_plus4")
Out[38]: '71875-8723'

my_list

my_list[:10]
Out[57]: 
[['administrative_unit', 'faker.administrative_unit()'],
 ['am_pm', 'faker.am_pm()'], ...
