There is fat in all pastry, it is an essential ingredient.
********************
The fat (butter) is folded into the dough time and time again until there are many, many layers of fat and dough. When baked, the fat melts and produces steam which expands and puffs up the dough which bakes into the flaky shape caused by the steaming butter.

The dough used to make Puff pastry and Danish pastry is folded many times to create the multiple flaky layers of crisp baked pastry.
In baking, a puff pastry is a light, flaky, leavened pastry containing several layers of fat which is in solid state at 20 °C (68 °F). In raw form, puff pastry is a dough which is spread with solid fat and repeatedly folded and rolled out (never mashed, as this will destroy layering) and used to produce the aforementioned pastries. It is sometimes called a "water dough" or détrempe.
The fat lumps separate the layers of dough, producing flaky pastry.
Puff pastry involves layering butter into a shortcrust pastry, then completing a process of folding and rolling and folding again, in order to obtain many thin layers of butter spread within thin layers of pastry. When the pastry cooks, the fat in the butter keeps the layers separate, while the water content expands into steam and forces the layer apart. In a rough puff pastry, chunks of butter in mixed onto the pastry as it is made, and the pastry mix needs only be rolled once. with the lumps of butter within the pastry, the same effect happens, but over a small localised areas. The effect is the same, but the rough puff doesn't rise quite as much, and finishes with a rough texture. It is, of course, much quicker to make. Use it when the pastry will not be on show, such as for the base of tarts and the like.

Beurrage is the butter block that is used in the production of puff pastry. It is also referred to as the "roll-in fat" because it is rolled between the layer of the detrempe (dough part of puff pastry). The steam released from the beurrage during the baking process is what causes the natural leavening effects and multiple layers in puff pastry.

hai iam haroon, The difference is in the apply of fat on the flour. In puff pastry the fat is spread on the rolled dough, where as in shortcrust the fat and flour is mix into sandy like texture using finger tips or icing spatcula.
No, puff pastry is often purchased in the freezer section of the store next to the frozen pies and pie crusts. Puff pastry is painstakingly created by folding and rolling out sheets of dough with layers of butter so that when they bake the water in the butter creates steam and "puffs" the layers of dough, creating the soft, flaky texture that puff pastry is known for. Won ton wrappers are more closely related to pasta dough I believe.
