Python Hot to use output form one class method in another class method

Question

I have class method generated_username which is generate string and return that string, and I need to use this output in another method new_full_list, but I get run the whole method not just its output Here is my code:

class Users():

def generated_username(self, driver):
    username = driver.find_element_by_css_selector("[id=systemUser_employeeName_empName]").get_attribute('value')
    username = username.replace(' ', '').lower()
    username = username + ''.join(random.choice(string.digits) for i in range(3))
    return username

def new_full_list(self,driver):
    l = driver.find_elements_by_xpath("//*[@class='odd' or @class='even']/td[2]/a")
    l = [x.text for x in l]
    l.append(self.generated_username(driver))

What is the current output you are receiving, and what do you want it to be instead? Your question is not too clear. — DMe

@Windmill in line l.append(self.generated_username(driver)) i want to append string which is created in generated_username but instead of this generated_username runs again (try to find element driver.find_element_by_css_selector("[id=systemUser_employeeName_empName]").get_attribute('value')) and then generate string and then return, but in that time i already on different page, so driver can not find this element driver.find_element_by_css_selector("[id=systemUser_employeeName_empName]").get_attribute('value') — Ihor Harmatii

If I understand correctly, you would like generated_username to be called on a particular page, and generate a string. Later, on a different page, you want to use that earlier generated string in new_full_list.

To do this, you could create a class variable to hold this string.

class Users():
    user_string = ""

Then, when on the correct page (I'm not sure what the rest of your code looks like/how you control the flow/when functions are called), you call generated_username(driver). We will modify generated_username to set the class variable we created earlier.

def generated_username(self, driver):
    ...
    <s>return username</s>
    this.user_string = username

When you later call new_full_list(driver) on a different page, you want it to use this previous value. We can do that as follows:

def new_full_list(self,driver):
    l = driver.find_elements_by_xpath("//*[@class='odd' or @class='even']/td[2]/a")
    l = [x.text for x in l]
    l.append(self.user_string)

Right now, you are calling generated_username inside new_full_list, which means the entire function runs, including the find_element etc.
