python - 一起返回而不是逐一返回

Question

有多个Content-child。但结果会 1 对 1 地返回。

element1 = driver.find_element_by_xpath("//div[@id='Content']")
element2 = driver.find_elements_by_xpath("//div[@class='Content-child']")

for element3 in element2:
    element3_list = element3.text

    df = pd.DataFrame(element3_list, columns=['a','b','c'])
    pd.set_option('display.max_colwidth', -1)
    print(tabulate(df, headers='keys', tablefmt='psql'))

----结果----

+--+----+----+----+
|   | a  | b  | c  |
+---|----+----+----+
| 0 | 3  | 1  | 21 |
+---+----+----+----+

+--+----+----+----+
|   | a  | b  | c  |
+---|----+----+----+
| 0 | 5  | 8  | 41 |
+---+----+----+----+

我所期望的是

+--+----+----+----+
|   | a  | b  | c  |
+---|----+----+----+
| 0 | 3  | 1  | 21 |
+---+----+----+----+
| 1 | 5  | 8  | 41 |
+---+----+----+----+

是循环错误还是有什么模块可以结合起来？

Answer 1

让我们将您的 df 恢复到 for 循环中的 list

l=[]
for element3 in element2:
    element3_list = element3.text

    l.append(pd.DataFrame(element3_list, columns=['a','b','c']))

df=pd.concat(l).reset_index(drop=True)
