160 If you want to replace multiple characters you can call the String.prototype.replace() with the replacement argument being a function that gets called for each match. All you need is an object representing the character mapping that you will use in that function.

On the other hand, replace() (another method given on this page) is a numpy.putmask operation (source). Because numexpr is a faster than numpy for large arrays, for very large dataframes, replace may be outperformed by the other methods. On a tangential note, it's common for a dataframe to have a literal string 'NaN' instead of an actual NaN value.
