将两个复数输入值的加法分配给python中的变量

Question

page_soups = []

for page in range(1, 51):

  url = 'https://etherscan.io/txs?p=' + str(page)

  print(url)

  req = Request(url, headers={'User-Agent': 'Mozilla/5.0'})

  webpage = urlopen(req).read()

  page_soup = soup(webpage, "html.parser").find('tbody').find_all('a')

  page_soups += page_soup

我使用循环来抓取多个网页，但只能获取前 30 页的数据。第31条有错误如下

错误

我检查该网页，发现它仍然具有与其他网页相同的标签和元素。请帮我。

确保以Python 期望的确切格式输入数字。num1 = complex(input("Enter a number: "))num2 = complex(input("Enter another number: "))print(f"{num1} + {num2} = {num1 + num2}")print(f"{num1} - {num2} = {num1 - num2}")print(f"{num1} * {num2} = {num1 * num2}")print(f"{num1} / {num2} = {num1 / num2}")工作得很好（尽管有浮点精度）：$ python3 socom.pyEnter a number: 2.44-77.3333jEnter another number: 6.83+15j(2.44-77.3333j) + (6.83+15j) = (9.27-62.333299999999994j)(2.44-77.3333j) - (6.83+15j) = (-4.390000000000001-92.3333j)(2.44-77.3333j) * (6.83+15j) = (1176.6646999999998-491.5864389999999j)(2.44-77.3333j) / (6.83+15j) = (-4.208867770125335-2.0791044579970688j)
