如何通过Pandas在csv中写入多个for循环数据时在单个单元格中追加数据?

How to append data in single cell while writing data of multiple for loop in a csv through Pandas?

问题:-

我在主 for 循环中有两个嵌套循环,用于从 5 页的范围内获取不同的数据。 每页有5行,但是将数据写入csv后,我只得到5个单元格,每个单元格有5个值。

我想要的解决方案 :-

我希望所有的日期和时间都在不同的行中,所以总共应该至少有 25 行。

我的最小代码 :-

all = []

for i in range(d, 0, -1):
    driver.find_element_by_link_text(f'{i}').click()
    time.sleep(5)
    c12 = []
    d12 = []

    date1 = driver.find_elements_by_class_name('Login_d')
    for i in reversed(date1):
        print(i.text)
        c12.append(i.text)
        if i is None:
            break

    date_time = driver.find_elements_by_class_name('Logout_d')
    for i1 in reversed(date_time):
        print(i1.text)
        d12.append(i1.text)
        if i1 is None:
            break

    z = [c12, d12]
    all.append(z)


 df = pd.DataFrame(all)
 path = 'C:\Application Data\pyt_project\datahub'
 a1 = ['Date', 'Date_time']
 filename = 
 dt.datetime.now().strftime("Login_logout_time_%d_%b_%y_%I_%M_%p.csv")
 p1 = os.path.join(path, filename)
 df.to_csv(p1, headers = a1, index=True)
 print('printed output')

我从上面的代码得到的 CSV 输出

                              Date                                        Date_time
 03 Nov 2021 08 Nov 2021 09 Nov 2021 10 Nov 2021 11 Nov 2021 | 18:39 12:59 13:05 12:57 12:57

我想要的 CSV 输出

   Date     Date_time
03 Nov 2021  18:39
08 Nov 2021  12:59
09 Nov 2021  13:05
10 Nov 2021  12:57
11 Nov 2021  12:57

我尝试过但没有成功的事情

df = pd.DataFrame({'Date' : [c12],
                'Date_time' : [d12]
                },
                columns=['Date', 'Date_time'])

注意 因为问题只考虑了部分代码,所以我假设之前发生的一切都有效,只进入明显的部分

I want all the dates as well as time to be in different rows

如果两个列表的长度相同,您可以简单地zip()它们:

pd.DataFrame(zip(c12,d12),columns=['Date', 'Date_time'])

例子

import pandas as pd

c12 = ['03 Nov 2021', '08 Nov 2021','09 Nov 2021','10 Nov 2021','11 Nov 2021']
d12 = ['18:39','12:59','13:05','12:57','12:57']

pd.DataFrame(zip(c12,d12),columns=['Date', 'Date_time'])

输出

Date Date_time
03 Nov 2021 18:39
08 Nov 2021 12:59
09 Nov 2021 13:05
10 Nov 2021 12:57
11 Nov 2021 12:57

But after writing data to csv, I only get 5 cells in which each cell has 5 values.

放置列表以使您的数据保持在循环之外并检查您的缩进。

c12 = []
d12 = []

for i in range(d, 0, -1):
    driver.find_element_by_link_text(f'{i}').click()
    time.sleep(5)

    date1 = driver.find_elements_by_class_name('GridBiMonthlyBonusEligibleListDatetd.NoSortColumn')
    for i in reversed(date1):
        print(i.text)
        c12.append(i.text)
        if i is None:
            break

    date_time = driver.find_elements_by_class_name('GridBiMonthlyBonusEligibleListLoginDatetd.NoSortColumn')
    for i1 in reversed(date_time):
        print(i1.text)
        d12.append(i1.text)
        if i1 is None:
            break

pd.DataFrame(zip(c12,d12),columns=['Date', 'Date_time'])#.to_csv(...)
