有任务
我们发现其阶乘的数字每次增加 2。如何在 Pascal 中实现它？这是代码：
const n = 3;
const f = 6;
var a, sin_a, sin_a1: real;
factorial,factorial1: longint;
i,i1: byte;
begin
write('введите а: ');
readln(a);
factorial:= 1;
factorial1:= 1;
for i := 2 to n do
factorial:= factorial * i;
for i1:= 2 to n1 do
factorial1:= factorial1 * i1;
sin_a:=a-((power(a,n)/factorial)+(power(a,n+2)/factorial+2));
sin_a1:= power(a,n+2)/factorial+2;
writeln('результат = ',sin_a);
writeln(sin_a1);
end.
制作了一个解析器，显示来自网站的经文文本：https :
//stihibase.ru/author/t/tjutchev/vesennjaja_groza/ 但是，除了文本之外，它还显示 block-poema-left-control 并写入：“按主题和作者”。我需要删除它
from bs4 import BeautifulSoup
import pandas as pd
url = 'https://stihibase.ru/author/t/tjutchev/vesennjaja_groza/'
response = requests.get(url)
bs = BeautifulSoup(response.text,"lxml")
temp = bs.find('article', 'block-poema')
print(temp.text)
