如何使用re.sub将硒字符串转换为整数 [英] How use re.sub to convert selenium string to an Integer

问题描述

我真的很希望他的最后几天将我的字符串值转换为整数，所以我尝试这样做:

快照:

代码试用:

  follower_count = int(browser.find_element_by_xpath('/html/body/div [1]/section/main/div/header/section/ul/li [2]/a/span').text)convert_follower_count = re.sub('[^ 0-9]'，''，follower_count) 

...不起作用:

  Traceback(最近一次通话最近):< module>中的文件"C:\ Users \ Desktop \ TwitPy \ quickstart.py"，第79行.followers_count = re.sub('[^ 0-9]'，''，follower_count)子目录中的文件"C:\ Users \ AppData \ Local \ Programs \ Python \ Python38 \ lib \ re.py"，第208行返回_compile(pattern，flags).sub(repl，string，count)TypeError:预期的字符串或类似字节的对象 

解决方案

提取的文本(即 1,961 )之间包含一个 字符.因此，您将无法直接在其上调用 int().

---

解决方案

您可以使用sub()tag> re 替换文本 1,961 中的，字符，然后按如下所示调用 int():

• 代码块:

   #follower_count = int(browser.find_element_by_xpath('/html/body/div [1]/section/main/div/header/section/ul/li [2]/a/span').text)计数="1,961".汇入print(int(re.sub('，'，''，count)))print(type(int(re.sub('，'，``，count))))) 

• 控制台输出:

    1961< class'int'> 

---

此用例

有效地，您的代码行将是:

  follower_count = int(re.sub('，'，``，browser.find_element_by_xpath('/html/body/div [1]/section/main/div/header/section/ul/li [2]/a/span').text))

I am really desperate his last days to convert my string numbers value to a integer, so i try this :

Snapshot:

Code trials:

follower_count = int(browser.find_element_by_xpath('/html/body/div[1]/section/main/div/header/section/ul/li[2]/a/span').text)
convert_follower_count = re.sub('[^0-9]','', follower_count)

... is not working :

Traceback (most recent call last):
 File "C:\Users\Desktop\TwitPy\quickstart.py", line 79, in <module>
   followers_count = re.sub('[^0-9]','', follower_count)
 File "C:\Users\AppData\Local\Programs\Python\Python38\lib\re.py", line 208, in sub
   return _compile(pattern, flags).sub(repl, string, count)
TypeError: expected string or bytes-like object          

解决方案

The extracted text i.e. 1,961 contains a , character in between. So you won't be able to invoke int() directly on it.

---

Solution

You can can use sub() from re to replace the , character from the text 1,961 first and then invoke int() as follows:

• Code Block:

  # follower_count = int(browser.find_element_by_xpath('/html/body/div[1]/section/main/div/header/section/ul/li[2]/a/span').text)
  count = "1,961"
  
  import re
  print(int(re.sub(',', '', count)))
  print(type(int(re.sub(',', '', count))))
  

• Console Output:

  1961
  <class 'int'>
  

---

This usecase

Effectively, your line of code will be:

follower_count = int(re.sub(',', '', browser.find_element_by_xpath('/html/body/div[1]/section/main/div/header/section/ul/li[2]/a/span').text))
