No specific qualifications are required to work as a painter & decorator. However, in seeking employment, a certain amount of on-site experience is usually required. This could include experience in building or construction, which would provide a foundation of the skills required to do the job effectively. A complete beginner could use an apprenticeship as a way of getting initial experience in the field. To apply for an apprenticeship, applicants would usually need GCSEs in Maths, English and Technology as a basic entry point. The apprenticeships website is a good source of information. Specific courses also exist both to provide initial experience, and to accompany the learning experience of a trainee who is already working for a company. These include:
You saw that, to define a decorator, you typically define a function returning a wrapper function. The wrapper function uses *args and **kwargs to pass on arguments to the decorated function. If you want your decorator to also take arguments, you need to nest the wrapper function inside another function. In this case, you usually end up with three return statements.
Modernism describes both a set of cultural tendencies and an array of associated cultural movements, originally arising from wide-scale and far-reaching changes to Western society in the late 19th century and early 20th century. Modernism was a revolt against the conservative values of realism. The term encompasses the activities and output of those who felt the "traditional" forms of art, architecture, literature, religious faith, social organization and daily life were becoming outdated in the new economic, social and political conditions of an emerging fully industrialized world. A salient characteristic of modernism is self-consciousness. This often led to experiments with form, and work that draws attention to the processes and materials used (and to the further tendency of abstraction).
Here we ensure that the key student_id is part of the request. Although this validation works, it really does not belong in the function itself. Plus, perhaps there are other routes that use the exact same validation. So, let’s keep it DRY and abstract out any unnecessary logic with a decorator. The following @validate_json decorator will do the job:
Modifying classes in this fashion is also possible, though the benefits are not as immediately apparent. Almost certainly, anything which could be done with class decorators could be done using metaclasses, but using metaclasses is sufficiently obscure that there is some attraction to having an easier way to make simple modifications to classes. For Python 2.4, only function/method decorators are being added.
Historically, the painter was responsible for the mixing of the paint; keeping a ready supply of pigments, oils, thinners and driers. The painter would use his experience to determine a suitable mixture depending on the nature of the job. In modern times, the painter is primarily responsible for preparation of the surface to be painted, such as patching holes in drywall, using masking tape and other protection on surfaces not to be painted, applying the paint and then cleaning up.
Painters prepare surfaces of building and other structures and then apply paint by means of brushes, rollers or sprayers. They work with varnish, enamels, lacquer and other materials. They may also paint interior rooms or cover walls with paper, fabrics, vinyls or other materials (paperhanger). They must be able to mix paints as well as do sandblasting and waterblasting.
If working inside a person’s home, special attention will need to be paid to the different problems that can be encountered, such as those presented by pets and furniture. It is also essential to respect the private space of the client, and to work appropriately within it. If working for a construction firm, dangerous situations can be encountered, such as working at heights and employing the use of safety harnesses and ropes. Working outside brings with it its own hazards and difficulties, and the worker will need to plan for these accordingly through the types of clothing worn and the equipment used. The days can be long, and the hours can vary significantly. If self-employed, planning is essential to fit in as many jobs as is appropriate for the week, in order to avoid long spells of little work, or booking too many jobs into a short period of time. It is also possible that some jobs will require unsociable hours of work, such as working at the weekend. Although the profession is traditionally male dominated, more women are now being encouraged into the trade.
Aerosol paint (also called spray paint) is a type of paint that comes in a sealed pressurized container and is released in a fine spray mist when depressing a valve button. A form of spray painting, aerosol paint leaves a smooth, evenly coated surface. Standard sized cans are portable, inexpensive and easy to store. Aerosol primer can be applied directly to bare metal and many plastics.

Painters must have manual dexterity as well as steady nerves to work in high places. They should not be allergic to or bothered by paint fumes, toxic materials and spray dust. They should have a certain artistic sense in order to do a first-class job. Good eyesight and sense of color is especially important to properly mix paint to specific colors.
The oldest known paintings are at the Grotte Chauvet in France, which some historians believe are about 32,000 years old. They are engraved and painted using red ochre and black pigment, and they show horses, rhinoceros, lions, buffalo, mammoth, abstract designs and what are possibly partial human figures. However, the earliest evidence of the act of painting has been discovered in two rock-shelters in Arnhem Land, in northern Australia. In the lowest layer of material at these sites, there are used pieces of ochre estimated to be 60,000 years old. Archaeologists have also found a fragment of rock painting preserved in a limestone rock-shelter in the Kimberley region of North-Western Australia, that is dated 40,000 years old. There are examples of cave paintings all over the world—in Italy, France, Spain, Portugal, China, Australia, Mexico, etc. In Western cultures, oil painting and watercolor painting have rich and complex traditions in style and subject matter. In the East, ink and color ink historically predominated the choice of media, with equally rich and complex traditions.
