Can't use list from another file in Python

Question

I have a script that imports a list from another file. The list contains an almost-dictionary, so I ran a loop through it to turn it into a dictionary, but I'm getting the following error:

Redefinition of unused productOrdersListPulled

What am I doing wrong?

My code is:

import ast
import re
from api import productOrdersListPulled

# This script removes some  characters from the messy dictionaries,
# Afterwards, they are a dictionary, recognizable by python

# regex to find unneeded data in the file
order_item = re.compile("<OrderProducts at 0x[\da-f]+, ({.*?})>", re.I)


def transformInDictionary(productOrdersListPulled):

    # opens up the file with the unstructured data, and use it as a iterator

        for line in productOrdersListPulled:
            productOrdersListWithLine = [ast.literal_eval(op) for op in re.findall(order_item, line)]
        return productOrdersListWithLine

transformInDictionary()

And the other file is:

import bigcommerce

# Script used to pull OrderProducts data from the Big Commerce API.

# login to bigcommerce api
api = bigcommerce.api.BigcommerceApi(host='*******.mybigcommerce.com', basic_auth=('**********', '*************'))


# create lists
def createLists():

    productOrdersList = list()
    ordersList = list()
    productsList = list()
    return productOrdersList, ordersList, productsList


# update range if orders ids goes higher than this
# try,except, pass added so the for loop keeps looping even if IDs are not found
# remember to update range (higest so far: 615982)
def pullOrdersProductsData(productOrdersList):
    for x in range(614530, 614535):
        try:
            productOrdersList.append(api.Orders.get(id="{}".format(x)).products())
        except:
            pass
    return productOrdersList


# loop over the list and get the orders with the IDs
def pullOrders(ordersList):
    #  remember to update range (higest so far: 615982)
    for x in range(614534, 614535):
        try:
            ordersList.append(api.Orders.get(id="{}".format(x)))
        except:
            pass
    return ordersList


def pullProductsData(productsList):

    # loop over the list and get the products with the Ids
    # dont forget to update range (highest so far 2000)
    for x in range(0, 5):
        try:
            productsList.append(api.Products.get(id="{}".format(x)))
        except:
            pass
    return productsList

productOrdersListPulled, ordersListPulled, productsListPulled = createLists()
pullOrdersProductsData(productOrdersListPulled)
pullOrders(ordersListPulled)
pullProductsData(productsListPulled)

You are importing productOrdersListPulled from api;

from api import productOrdersListPulled

and your function transformInDictionary takes an argument with the same name.

def transformInDictionary(productOrdersListPulled):

You should rename the argument of your function.

def transformInDictionary(lst):
    for line in lst:
        productOrdersListWithLine = [ast.literal_eval(op) for op in re.findall(order_item, line)]
    return productOrdersListWithLine

And call it as follows: (last line of your script)

transformInDictionary(productOrdersListPulled)

How do I pass the productOrdersListPulled to transformInDiciontary if I use a different name?

Since you seem to want to use it as a global, you wouldn't as you don't need to.

First , i think your parameter name is too conflict .

Moreover , your method signature probably incorrect ? transformInDictionary take one argument , but you call with zero argument

I think this may solve your problem ?

from api import productOrdersListPulled as products #Give alias to productOrdersListPulled
def transformInDiction():
    """
    Change to zero argument
    """
    for line in products :
        product= [ast.literal_eval(op) for op in re.findall(order_item, line)]
    return product
transformInDiction()
