变量在嵌套循环内丢失引用

Question

我的变量tag在输入嵌套for时失去了引用：

file_with_all_tags = open("tags.txt", "r")
origem = open("origem.html", "r")

for tag in file_with_all_tags:

    final_file_name = "tag-" + tag + ".html"
    final_file = open(final_file_name, "w")

    for line in origem:
        if tag in line: # HERE THE VARIABLE 'TAG' IS EMPTY
            final_file.write(line)

    final_file.close()

origem.close()
file_with_all_tags.close()

Answer 1

问题解决了！实际上我对文件＆＃34; origem.html＆＃34;的迭代很累。我不得不将open（）和close（）函数移动到循环内部。多谢你们！谢谢@rrauenza！
