python3-utils

This repository contains a set of libraries that I use in other projects

Installation

Installation can be done through the pip3 command:

pip3 install procamora-utils --user

You can also update the library with:

python3 -m pip install --user --upgrade procamora-utils

Libraries

• logger
• interface_sqlite
• ip
• ping
• client_ssh

logger

Library to run the logging library with colors according to the type of log.

Basic Usage

To use this class the first thing to do is import the library:

import logging
from procamora_utils.logger import get_logging

logger: logging = get_logging(verbose=False, name='test')

logger.debug('hi')
logger.info('hi')
logger.warning('hi')
logger.error('hi')
logger.critical('hi')

interface_sqlite

This library provides an easy way to manage a sqlite database. To do this, use the sqlite3 library to connect to the database and the logging library to display information about errors and debugging.

Basic Usage

To use this class the first thing to do is import the library:

from procamora_utils.logger import get_logging
from procamora_utils.interface_sqlite import *

The interface_sqlite file when doing an import * we are importing three functions, these are:

__all__ = ['conection_sqlite', 'execute_script_sqlite', 'dump_database']

conection_sqlite

This function is responsible for carrying out the main SQL operations, such as: SELECT, INSERT, UPDATE or DELETE.

An example of some of these functions would be:

from pathlib import Path
from typing import List, Dict, Text, Any
from procamora_utils.interface_sqlite import *

db: Path = Path('database.db')
def select_all_hosts() -> List[Dict[Text, Any]]:
    query: Text = "SELECT * FROM Hosts"
    response_query: List[Dict[Text, Any]] = conection_sqlite(db, query, is_dict=True)
    return response_query

def update_host_offline(date: Text):
    query: Text = f"UPDATE Hosts SET active=0 WHERE date <> '{date}';"
    conection_sqlite(db, query)

Parameterized query

This library allows the Parameterized of sql queries, here is an example of how to use it

from pathlib import Path
from typing import List, Dict, Text, Any, Tuple
from procamora_utils.interface_sqlite import *
db: Path = Path('database.db')

query: Text = "SELECT * FROM table1 WHERE value=?"
params: Tuple = ('Python',)
response_query: List[Dict[Text, Any]] = conection_sqlite(db, query, query_params=params, is_dict=True)

execute_script_sqlite

This function allows you to run a script or dump that you receive in string format. With this function, databases could be created.

from pathlib import Path
from typing import Text
from procamora_utils.interface_sqlite import *

db: Path = Path('database.db')
dump: Text = '''INSERT INTO() VALUES();
INSERT INTO() VALUES();'''
execute_script_sqlite(db, dump)

dump_database

This function allows you to perform a complete dump of the database.

from pathlib import Path
from procamora_utils.interface_sqlite import *

db: Path = Path('database.db')
response = dump_database(db)

ip

This library provides a high-level abstraction for storing an IP address or FQDN. In case of entering a wrong value it will raise an exception.

Basic Usage

import logging
from typing import Text

from procamora_utils.ip import IP
from procamora_utils.logger import get_logging
logger: logging = get_logging(False, 'ip')


fqdn: Text = 'google.es'
ip: IP = IP(fqdn=fqdn)
logger.info(ip.get_addr())

ipv4: Text = '192.168.1.1'
ip: IP = IP(ip=ipv4)
logger.info(ip.get_addr())

ping

This library provides an easy way to ping using the ping command provided by the operating system. The reason for using the operating system command is so that you do not need to be root to send an ICMP packet.

Basic Usage

To use this class the first thing to do is import the library:

import logging
from typing import List
from procamora_utils.ip import IP
from procamora_utils.ping import ping
from procamora_utils.logger import get_logging
logger: logging = get_logging(False, 'ping')

ips: List[IP] = [IP(ip="127.0.0.1"), IP(ip="192.168.0.103"), IP(fqdn="google.es"), IP(fqdn="google.false")]
for ip in ips:
    texto: bool = ping(ip)
    if texto:
        logger.info("{} up".format(ip.get_addr()))
    else:
        logger.info("{} down".format(ip.get_addr()))

client_ssh

This library provides a high-level abstraction for storing an IP address or FQDN. In case of entering a wrong value it will raise an exception.

Basic Usage

import logging
from typing import Text

from procamora_utils.ip import IP
from procamora_utils.logger import get_logging
logger: logging = get_logging(False, 'ip')


fqdn: Text = 'google.es'
ip: IP = IP(fqdn=fqdn)
logger.info(ip.get_addr())

ipv4: Text = '192.168.1.1'
ip: IP = IP(ip=ipv4)
logger.info(ip.get_addr())

ping

This library provides an easy way to use the ssh command, allowing you to connect unattended over SSH and thus facilitating process automation tasks.

Basic Usage

To use this class the first thing to do is import the library:

from procamora_utils.logger import get_logging, logging
from procamora_utils.client_ssh import create_arg_parser, ClientSSH
logger: logging = get_logging(False, 'ping')

args = create_arg_parser()

ssh: ClientSSH = ClientSSH(args.ip, args.port, args.verbose)
output = ssh.execute_command(user=args.user, password=args.pwd, cert=args.key, sudo=args.sudo)
print(output)
