This looks wrong on several counts:

1) apply() usually takes a function object as the first argument not the
return value of a function call as here.

2) When calling a function using keyword arguments you re not allowe to
have non-keyword arguments following the keyword ones, so the df[...]
bit should be an error

3) The df['loanage] does not have a closing quote.

I'm not sure if any of the above would result in a ValueError
but its possible.
