使用python批量讀取文件並修改生成新的文件

問題

假設有一個文件，文件里包含一個地址，現在有幾十上百個這種地址，這些地址所對應的文件除了地址其他的配置都是相同的，所以，怎么以其中一個文件為模板，替換其中的地址，然后批量生成幾十個這種文件呢？

話不多說，直接上代碼，十幾行代碼就可以解決此問題。

def copyAppScanTemplate(target_file, target_url):
    with open("G:\\appScanTemplate\\alpha\\alpha-cloud.scan", 'r') as f_read:
        file_read = f_read.readlines()
        replace_str = "<StartingUrl>https://alpha-cloud.yunshicloud.com/</StartingUrl>"
        for line in file_read:
            with open(target_file, "a+") as f_write:
                if replace_str in line:
                    new_line = line.replace(replace_str, target_url)
                    f_write.write(new_line)
                else:
                    f_write.write(str.encode(line))

def startcp():
    with open("G:\\appScanTemplate\\alpha\\domain.txt", 'r+') as fr:
        file_read = fr.readlines()
        count = 0
        for line in file_read:
            target_url = "<StartingUrl>https://{}/</StartingUrl>" .format(line.strip('\n').strip())
            target_file = "G:\\appScanTemplate\\alpha\\" + line.split('.')[0] + ".scan"
            copyAppScanTemplate(target_file, target_url)
            count += 1
            print(count)

if __name__ == "__main__":
    startcp()

 

domain.txt這個就是存放我們要替換的所有域名，例如：

domain.txt

www.a.com
www.b.com
www.c.com
...
...
...
