Python Selenium xpath with variable

Question

我不能在变量中传递我对selenium的xpath搜索。我错在哪里?

btn_login = "'.//a[contains(text(), 'Login to')]'"
btn = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.XPATH, f'{btn_login}')))​
btn.click()

---

就像它可以工作一样，我不知道在这种情况下是否可以使用f字符串

btn = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.XPATH, .//a[contains(text(), 'Login to')]')))
btn.click()

Answer 1

如果您希望"Login to"文本来自变量，请这样做:

text = "whatever"
btn_login = f".//a[contains(text(), '{text}')]"
btn = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.XPATH, btn_login)))​
