Python script that deletes symbols in plain text

[nzcan]

I need a python script that deletes all symbols in a plain text file.
For example, I want that all 'd', all 'f' and all '0' (zeros) in a plain text file to be deleted and not replaced by other symbols.

Is open() good for this task or I should use something else?

Thanks i advance!

You cannot delete things from a file. You can read a file and write a new file that has the contents of the old sans the unwanted symbols.

There are tools that do this kind of thing. What operating system are you using.
