使用Python将包含逗号的抓取字符串转换为整数 [英] Convert a scraped string containing comma into an integer using Python

问题描述

我正在尝试用硒来消除追随者的数量，但可以清楚地识别出"ValueError"错误.作为数字:

快照:

代码试用:

  follower_count = int(browser.find_element_by_xpath('/html/body/div/div/div/div/div [2]/main/div/div/div/div [1]/div/div [2]/div/div/div[1]/div/div[5]/div[2]/a/span[1]/span').text)following_count = int(browser.find_element_by_xpath('/html/body/div/div/div/div/div [2]/main/div/div/div/div/div [1]/div/div [2]/div/div/div[1]/div/div [5]/div [1]/a/span [1]/span').text) 

错误消息:

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

您需要先从文本 1,961 中对，字符进行 replace()，然后调用 int()如下:

• 代码块:

   #count = browser.find_element_by_xpath('/html/body/div/div/div/div/div [2]/main/div/div/div/div/div [1]/div/div [2]/div/div/div [1]/div/div [5]/div [2]/a/span [1]/span').text计数="1,961".print(int(count.replace(，"，"))))print(type(int(count.replace(，"，"))))) 

• 控制台输出:

    1961< class'int'> 

---

此用例

有效地，您的代码行将是:

  follower_count = int(browser.find_element_by_xpath('/html/body/div/div/div/div/div [2]/main/div/div/div/div [1]/div/div [2]/div/div/div [1]/div/div [5]/div [2]/a/span [1]/span').text.replace(，"，"))following_count = int(browser.find_element_by_xpath('/html/body/div/div/div/div/div [2]/main/div/div/div/div/div [1]/div/div [2]/div/div/div[1]/div/div [5]/div [1]/a/span [1]/span').text.replace(，"，")))

Im trying to scrape the number of followers count with selenium but it clearly identify the "ValueError" as a number:

Snapshot:

Code trials:

follower_count =int(browser.find_element_by_xpath('/html/body/div/div/div/div[2]/main/div/div/div/div[1]/div/div[2]/div/div/div[1]/div/div[5]/div[2]/a/span[1]/span').text)
following_count = int(browser.find_element_by_xpath('/html/body/div/div/div/div[2]/main/div/div/div/div[1]/div/div[2]/div/div/div[1]/div/div[5]/div[1]/a/span[1]/span').text)
        

The error message:

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 need to replace() the , character from the text 1,961 first and then invoke int() as follows:

• Code Block:

  # count = browser.find_element_by_xpath('/html/body/div/div/div/div[2]/main/div/div/div/div[1]/div/div[2]/div/div/div[1]/div/div[5]/div[2]/a/span[1]/span').text
  count = "1,961"
  print(int(count.replace(",","")))
  print(type(int(count.replace(",",""))))
  

• Console Output:

  1961
  <class 'int'>
  

---

This usecase

Effectively, your line of code will be:

follower_count =int(browser.find_element_by_xpath('/html/body/div/div/div/div[2]/main/div/div/div/div[1]/div/div[2]/div/div/div[1]/div/div[5]/div[2]/a/span[1]/span').text.replace(",",""))
following_count = int(browser.find_element_by_xpath('/html/body/div/div/div/div[2]/main/div/div/div/div[1]/div/div[2]/div/div/div[1]/div/div[5]/div[1]/a/span[1]/span').text.replace(",",""))
