right now I'm trying to convert the juliet dataset into a pandas dataframe. I converted all the .cpp, .c and .h files into .txt files and am now trying to transfer those text files into a pandas dataframe. To do this, I'm using the read_table function in pandas, but I want every file to have its own cell. Is there any way I can get rid of separators for this function so each txt file gets one cell without being seperated.
