Hello, Can anybody try to help me please with the indentation issue in my below code?

"I am new to selenium python and trying to learn" I have added if condition and also while loop but looks like I am getting lost with the indentations of it . Its giving me for the below line::

driver.find_element_by_xpath("//div[@class='v-horizontallayout v-horizontallayout-x-horizontal-layout x-horizontal-layout']//Span[contains(text(),'Post')]").click()

Error is: Unable to locate element: (but this was working fine before)

Below is my code :

if  Currency [0] == '€':
    print("Hello, I am printing €, as I am in Euro til")
    driver.find_element_by_xpath(
        "//div[@class='v-customcomponent v-customcomponent-gk-action-bar gk-action-bar v-customcomponent-portal-menu-actionbar portal-menu-actionbar']//Span[contains(text(),'Drawer')]").click()
    driver.find_element_by_xpath(
        "//div[@Class='v-tree-node-caption']//Span[contains(text(),'Drawer Accounts')]").click()
    driver.switch_to.frame(1)
    print("I am inside frame")
    wait.until(EC.element_to_be_clickable((By.XPATH, ".//span[text()='Account']"))).click()
    print("I have cliked on Account")
    time.sleep(2)
    current_loan = driver.find_element(By.XPATH,"//div[contains(text(),'Current Loan/Change Amount')]/ancestor::div[contains(@class,'horizontallayout')]/../../following-sibling::div/descendant::input").get_attribute('value')
