我有以下数据帧:
A B C
I am motivated Agree 4
I am motivated Strongly Agree 5
I am motivated Disagree 6
I am open-minded Agree 4
I am open-minded Disagree 4
I am open-minded Strongly Disagree 3

如果列A是问题,则列B是答案,列C是A列中问题的"强烈同意","同意","不同意"和"非常不同意"的频率.
如何将其转换为以下数据帧?
Strongly Agree Agree Disagree Strongly Disagree
I am motivated 5 4 6 0
I am open-minded 0 4 4 3

这与我之前的问题类似:使用三列的分组问题创建一个数据框
我尝试用stack/pivot查看之前的问题,但无法弄明白.实际的数据框架有20多个问题和一个强烈同意,同意,中立,不同意,强烈不同意的类似规模.
您好,我想在当前列中使用str和int添加一个前导零,但我不知道如何。我只想在数字ex前面加上零:而不是A111。数据是从csv文件导入的。我对熊猫和python很陌生。
例如:

有没有更好的方法来初始化具有不同K值和范围()的多个(5+)列表?
例如:
y = [(''.join(random.choices(string.ascii_lowercase, k=3))) for _ in range(5)]
z = [(''.join(random.choices(string.ascii_lowercase, k=7))) for _ in range(2)]
a = [(''.join(random.choices(string.ascii_lowercase, k=4))) for _ in range(3)]
b = [(''.join(random.choices(string.ascii_lowercase, k=3))) for _ in range(5)]
c = [(''.join(random.choices(string.ascii_lowercase, k=1))) for _ in range(3)]

运行时循环会滞后,有时在图像加载后长达 10 秒。我的机器本身速度很快(i7 16gb 内存等)。有什么办法可以加快这个循环吗?
我正在加载网页,因此“主页”按钮不会立即出现。此循环发生在 pyautogui 输入要加载的网址后。
