Two errors, the first spelling of
return, the second attempting to return a statement.
return can only pass a value, not a statement.
Value can be interpreted as expression, which includes a function call, or a function itself.
Three errors, actually. There is not such thing as,
text - letter
as strings are concerned. There is no way to actually remove a letter from a string. We have to manipulate it and store it back in a variable (which can be the same one, this is reassignment--totally valid).
