PETSc comes with a large number of example codes to illustrate usage. The three main sets are in:

Several examples are also included that represent the interoperability with other numerical software packages in the xSDK Toolkit. These packages can be automatically installed by PETSc by configuring with --download-trilinos, --download-hypre, and/or --download-superlu_dist.
