How to remove two elements from a string in python where the elements appears as $[\text{'}$a $\backslash$tb$\backslash$tc$\backslash$td

$\text{'}.....]$ and want to both the remove the t$\text{'}$s and the n$\text{'}$s from the string. I am using the code: File$\_$content$=[]$ then I type: for i in File$\_$read: in the next line then indent and type File$\_$content.append $($i$.$split$(\text{'}\backslash$t$\text{'}))$ in the next line but it only removes the ts$.$ If I replace the $\text{'}$t$\text{'}$ with an $\text{'}$n$\text{'}$ the t$\text{'}$s reappear and the n$\text{'}$s go away. I need them both to go away.
