[英]how to copy content of file to another file with deleting some lines in a TXT file based on some strings with python
i have this python script that open a file dialog and select a text file than copy its content to another file, what i need to do before i copy to the next file is to delete several lines based on some strings that are predefined in the script.我有这个 python 脚本,它打开一个文件对话框并选择一个文本文件而不是将其内容复制到另一个文件,在复制到下一个文件之前我需要做的是根据脚本中预定义的一些字符串删除几行.
the problem is that the file is copied as it is without deleting anything.问题是文件按原样复制而没有删除任何内容。
can anyone help me to solve this issue??谁能帮我解决这个问题??
