Fragmentation functions are non perturbative objects which are needed to absorb consistently the singularities which appear in a perturbative QCD calculation. These objects are only known by comparing the experimental data and the theoretical predictions. Moreover, these objects are also important in order to test the factorization of the theory which impose also the universality of them. In this talk, we review the theoretical tools which are used for the extraction of the parton-to-pion fragmentation functions. Then, we show the results on the global NLO QCD fit to the data coming from single inclusive electron-positron annihilation, semi-inclusive deep-inelastic scattering and hadron-hadron collisions.
