用完成的多个循环替换 for 循环中的部分字符串

Question

如何使用已完成的循环数更改字符串的某个部分？我正在使用 Chromedriver (find_element_by_xpath) 从网站上抓取数据。我看到当 for 循环计数超过 10 时会出现问题。在计数达到 10 之前，它已经能够将 /tr[1] 替换为 /tr[2] 等等，但是一旦出现两位数，事情就会变得复杂。count = 0for i in range(0, 21):    count += 1    string[65] = str(count)    string = ''.join(string)    print(string)    string = list(string)The output is://*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[1]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[2]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[3]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[4]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[5]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[6]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[7]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[8]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[9]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[10]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[110]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[1210]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[13210]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[143210]/td[2]//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[1543210]/td[2]

Answer 1

尝试这个 ：

string = "//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[1]/td[2]"

all_list = [string[:65]+str(i+1)+string[66:] for i in range(0,15)]

print(*all_list, sep='\n')

输出：

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[1]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[2]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[3]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[4]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[5]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[6]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[7]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[8]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[9]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[10]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[11]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[12]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[13]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[14]/td[2]

//*[@id='teams_wrapper']/div[2]/div[3]/div[2]/div/table/tbody/tr[15]/td[2]
