将一个文件的 fun var 值访问到另一个 fun 或另一个 python 文件的 fun 之外？

Question

我有三个 python 文件问题是我正在尝试访问 test.py 文件中 sample.py 中定义的变量（“用户名”），因此我可以使用该变量或任何其他变量的值并将其传递给函数，或者如果我可以直接访问 test.py

的函数（test_target）中的任何变量值

sample.py

from configparser import ConfigParser

parser = ConfigParser()
parser.read('config.ini')


def GetEnviornment():
    env = input("Enter Environment name : ") or 'Dev Site'
    return env

def GetConnectionString():
    env = GetEnviornment()
    username = parser.get(env, 'username')
    password = parser.get(env, 'password')
    dbname = parser.get(env, 'dbname')

    return "%s/%s@%s" % (username, password, dbname)

connection.py

import cx_Oracle
import sample

class Connection(cx_Oracle.Connection):

    def __init__(self):
        connectString = test.GetConnectionString()
        print("CONNECT to database")
        return super(Connection, self).__init__(connectString)

    def cursor(self):
        return Cursor(self)


class Cursor(cx_Oracle.Cursor):

    def execute(self, statement):
        print("EXECUTE", statement)
        return super(Cursor, self).execute(statement)

    def fetchall(self):
        print("FETCH ALL")
        return super(Cursor, self).fetchall()

test.py

from connection import *    
from sample import *

def test_target(user_suffix,hash_value):
    connection = Connection()
    cursor = connection.cursor()
    cursor.execute("select * from dba_users u where u.USERNAME like '{}'".format(username))
    rows = cursor.fetchall()
    for row in rows:
        print(row)
    cursor.close()
    connection.close()

user_suffix="Hello"
hash_value="12345"
test_target(user_suffix,hash_value)

Answer 1

我在 test.py.you 中进行了更改，可以从连接中提取您想要的任何条目，例如用户名、dsn。 Connection class

中还有其他函数

from connection import *    
from sample import *

def test_target(user_suffix,hash_value):
    connection = Connection()
    cursor = connection.cursor()
    username = connection.username
    cursor.execute("select * from dba_users u where u.USERNAME like '{}'".format(username))
    rows = cursor.fetchall()
    for row in rows:
        print(row)
    cursor.close()
    connection.close()

user_suffix="Hello"
hash_value="12345"
test_target(user_suffix,hash_value)

将一个文件的 fun var 值访问到另一个 fun 或另一个 python 文件的 fun 之外？

Access the fun var value of one file into another fun or outside the fun of another python file?
