Summary  Let f be a transcendental entire function. In this paper we will prove that if f is of finite order, then there exists at most one integer k≥2 such that ff^{(k)} may have nonzero and finite Picard exceptional value. We also give a class of entire functions which have no nonzero finite Picard values. If f is a transcendental meromorphic function, we obtain that for nonnegative integers n, n_{1}, ..., n_{k} with n≥1, n_{1}+...+n_{k}≥1, if δ(o,f)>3/(3n+3n_{1}+...+3n_{k}+1), then f^{n}(f^{l})^{n1}...(f^{k})^{nk} has no finite nonzero Picard values.
