Question

I have four python scripts with below code:

main.py

from new import Name1
from new2 import Name2

class Details:

    def __init__(self, id=0, vuse=True):
        assert(id > 0)
        self.id = id
        self.vuse = vuse

    def Main(self):
        try:
            self.dir = "/value/"
            ti = Name1(id = self.id, dir = self.dir)
            name = ti.getDay()
            print name
        except Exception, e:
            print "Failed with %s" % e

if __name__ == "__main__":
    at = Details(id = '1', vuse=True)
    at.Main()

new.py

class Name1:

    def __init__(self,id,dir=''):
        self.id = id
        self.dir = dir

    def getDay(self):
        try:
            if id == 1:
                self.day = "monday"
                print "Name %s" % self.day
                return self.day
            else:
                self.day = "Another"
                print "Day %s" % self.day
                return self.day
        except Exception, e:
            print "ERROR : %s" % e

new2.py

from find import Find
from main import Details

class Name2:

    def getitems(self):
            self.id = "// This value i want from main.py or new.py script"
        at = Find(id = self.id )
        val = at.value()
        print val

if __name__ == "__main__":
    a = Name2()
    a.getitems()

find.py

class Find:

    def __init__(self, id):
        self.id = id

    def value(self):
        if self.id == 1:
            print "Right value"
            ##// Do some operation with id//

        else:
            print "invalid"

My problem is how can i access the id value in new2.py…
if I will take the value from main.py, for calling the class i need to pass the id value which new2.py does not have. The same thing for new.py also, i need id to create an object of a class.

It’s not clear how your program is supposed to work, but you can initialize id in an instance of Name2 when you create it:

def Main(self):
    self.dir = "/value/"
    ti = Name1(self.id, self.dir)
    ti_2 = Name2(self.id)

class Name2:
    def __init__(self, id):
        self.id = id

or pass it to getitems as an argument:

def Main(self):
    self.dir = "/value/"
    ti = Name1(self.id, self.dir)
    ti_2 = Name2()
    ti_2.getitems(self.id)

class Name2:
    def getitems(self, id):
        self.id = id
