selenium记录Spiderbuf例题C01

防止自己遗忘，故作此为记录。

步骤：

（1）进入例题，找到需要点击的元素。

可得button xpath：

复制代码

click_xpath: str = r'//li/a[@title="mnist"]'
WebDriverWait(driver, 10).until(expected_conditions.element_to_be_clickable((By.XPATH, click_xpath)))
res = driver.find_element(By.XPATH, click_xpath)

注意，此时点击res的attribute是完整url。(卡顿在此步，以为url还需要拼接)

之后发现：

可得final_xpath:

复制代码

final_xpath: str = r"//tbody/tr/td[2]"
WebDriverWait(driver, 10).until(expected_conditions.visibility_of_element_located((By.XPATH, final_xpath)))
res: list = driver.find_elements(By.XPATH, final_xpath)

最后计算：

复制代码

res: list[float] = [eval(e.text) for e in res]
s: Decimal = Decimal("0.0")

for each in res:
    s += Decimal(each)
s /= len(res)

print(f"{s=}")

s2=Decimal('3.766666666666666666666666667')
#四舍五入为3.77

完整代码：

driver.get(first_url)

click_xpath: str = r'//li/a[@title="mnist"]'
WebDriverWait(driver, 10).until(expected_conditions.element_to_be_clickable((By.XPATH, click_xpath)))
res = driver.find_element(By.XPATH, click_xpath)
driver.implicitly_wait(3)

driver.get(res.get_attribute("href"))

#WebDriverWait(driver, 10).until(lambda driver: driver.current_url != first_url)
final_xpath: str = r"//tbody/tr/td[2]"

WebDriverWait(driver, 10).until(expected_conditions.visibility_of_element_located((By.XPATH, final_xpath)))
res: list = driver.find_elements(By.XPATH, final_xpath)

res = [eval(e.text) for e in res]
length: int = len(res)

s1: float = sum(res) / length

s2: Decimal = Decimal("0.0")

for each in res:
    s2 += Decimal(each)

s2 /= length

print(f"{s1=}", f"{s2=}")

driver.close()
