求助想找出一组数据的最小值，但是这组数据是不确定个数的
for i in range(1,6):try:
in1=driver.find_element(By.XPATH,f'/html/body/mw/con/table/tbody/tr[{i}]/td').get_attribute('textContent')
in1=in1
match i:
case 1:
one=eval(in1)
case 2:
two=eval(in1)
case 3:
three=eval(in1)
case 4:
four=eval(in1)
case 5:
five=eval(in1)
if one==min(one,two,three,four,five):
print('zhiliao1')
#a=driver.find_element(By.XPATH, f'/html/body/mw/con/table/tbody/tr').get_attribute('onclick')
#driver.execute_script(f'{a}')
elif two==min(one,two,three,four,five):
print('zhiliao2')
elif three==min(one,two,three,four,five):
print('zhiliao3')
elif four == min(one, two, three, four, five):
print('zhiliao4')
elif five == min(one, two, three, four, five):
print('zhiliao5')
except:pass
如上代码，one,two,three,four,five 这五个数据有时候肯能是其中四个找最小值，或者其中三个找最小值，
但是我写的这个代码（if one==min(one,two,three,four,five):）的问题所在是，如果不是五个量都有值的话，就不会运行找最小值 要处理这个问题，你可以在每个循环中创建一个空列表，然后将获取到的值附加到该列表中。这样，你可以在每次循环结束时使用min()函数找到列表中的最小值。以下是代码的修改版本：
from selenium.webdriver.common.by import By
from selenium import webdriver
driver = webdriver.Chrome()
min_values = []
for i in range(1, 6):
try:
in1 = driver.find_element(By.XPATH, f'/html/body/mw/con/table/tbody/tr[{i}]/td').get_attribute('textContent')
in1 = in1
value = eval(in1)
min_values.append((i, value))
except:
pass
if min_values:
min_item = min(min_values, key=lambda x: x)
min_index = min_item
print(f'zhiliao{min_index}')
else:
print('没有找到最小值')
这个代码会在每次循环中尝试查找元素并提取值。如果成功，它将把这个值添加到min_values列表中。在循环结束后，使用min()函数找到列表中的最小值，并输出对应的"zhiliao"文本。如果没有任何值被找到，程序会输出"没有找到最小值"。 isdkz 发表于 2023-4-25 09:55

谢谢！我刚才用很笨的方法实现了，很臃肿，看完您的解答，我觉得收获很多，并学习新方法去修改原来的代码，感谢！
