为变量分配两个值

Question

I will try and explain this as well as possible without giving too many details on what I'm trying to do.

I have a website Website1 with a product x that has a value of 1 I have another website Website2 with the same product x that has a value of 2.

The product "x" has two values that need to be paired. Does this happen using a tuple?

x = [1, 2]

On Website2 I need to check a list of line items one by one in a loop. When it finds product x and it matches the joined value of 2 from Website1 in the tuple, I need to then perform a function to change the fulfillment value, the move onto the next line item to perform the next check. Here's what I have so far and I'm not even certain if the logic is anywhere close.

x = [1, 2]

if Website1 == x:
LineItem.find_element_by_xpath('./td[4]/div/div/input').clear()
time.sleep(2)
LineItem.find_element_by_xpath('./td[4]/div/div/input').send_keys("1")

else:
LineItem.find_element_by_xpath('./td[4]/div/div/input').clear()
time.sleep(2)
LineItem.find_element_by_xpath('./td[4]/div/div/input').send_keys("0")

Answer 1

Yes, you can easily use tuples to assign two values to a variable (the entire tuple is being assigned to the variable):

x = (val1, val2)
x[0] == val1  # True
x[1] == val2  # True

Side note: [] defines a list, not a tuple. The latter is the immutable variant of the former

Answer 2

You should use tuples.

x = (1, 2)

To get the values from tuples you simply do:

x[0] to get the first value, x[1] for the next and so on.

Answer 3

myValues = (a, b, c)

This will create a tuple, in which you can store multiple values. To get the different values, just use myValues[0] to get the first element, for example.

Answer 4

You can use a tuple but you don't have to. It's just one way to do it. What you have in [] s is an array. You can use that also and if you add a third+ website, you won't have to change the data structure, you'll just add a new value, eg x = [1, 2, 3] so having the array makes it easier to expand later vs a tuple.

Now to the code. It's kinda hard to understand your logic without more explanation but this should address your problem (and simplify your code).

You will notice that both the if and else block have basically the same code. The only difference is "1" vs "0" in the send_keys() . You should do some reading on DRY and DRY practices but the core concept is Don't Repeat Yourself. Pull the repeated lines out into a method called set_fulfillment_value() (You might want to give it a more appropriate name).

def set_fulfillment_value(value)
    LineItem.find_element_by_xpath('./td[4]/div/div/input').clear()
    # time.sleep(2) # this is a bad practice and should be removed (it likely isn't needed here anyway)
    LineItem.find_element_by_xpath('./td[4]/div/div/input').send_keys(value)

Use the if to set the value to be sent and then pass that into the method.

x = [1, 2]
value = None
if Website1 == x[0]:
    value = "1"
else:
    value = "0"
set_fulfillment_value(value)

NOTE: I know naming is hard but you should work on better variable names. Website1 sounds like it might be better named something like product ? Also, LineItem isn't very python-y. line_item would probably be better.
