What accessories do beginners need to buy when they enter the SLR Nikon d7000 set? What's the exact price of the accessories?

I can't tell you the specific price Prices vary widely, and there are no necessary accessories. All accessories are according to your needs.

Generally speaking, it is necessary to:

Photo bag: As long as you go out often, this is definitely a must.

Lens pen or lens paper, blow: this is also necessary, you have to clean the camera.

LCD protection screen: protect the LCD screen.

Optional are:

Tripod: useful, especially in low light (such as night scene). I suggest you buy it when you need it (that is, don't buy it if you don't know when to use it now). The suggested price of the camera is around110. If you travel a lot, you should be more portable.

UV mirror: protective lens. It's not good not to buy this. If you don't buy it well, it will affect the imaging quality.

Hood: It's very useful when shooting outdoors. It can avoid glare and ghosts, and it also protects the lens (that thing sticks out so long, you can't easily let anything touch the lens, can you? )

Polarizer: landscape photography is almost essential (sometimes it is not felt, so it can't be taken off later), which can eliminate nonmetallic reflection (for example, it can make water clearer) and increase the saturation of photos (for example, the sky is bluer and the leaves are greener). With polarizer, there is no need to install a uv mirror (this does not mean that you can buy a polarizer without buying UV, after all, polarizers can't always be installed).

Soft light screen: It has the same function as the soft light cover, but it is only used for the small broken flash that comes with the camera (for that small broken flash, if you really don't want to buy it, you can use a translucent napkin instead), which is especially useful when taking portraits.

More advanced options are:

Suofang: It is useful when exposed for a long time, such as shooting night scenes and fireworks. Of course, if you don't often take pictures with this thing, don't buy it and use the self-timer function instead.

Flash: used to fill the light. It's so useful. The little broken flash that comes with the camera can't compare with it. Of course, don't buy it for novices. Let's talk about it later.

Flash soft cover: soft light, you don't have to buy this if you don't buy a flash.

These optional accessories are suggested as follows:

If you travel frequently and take pictures of scenery, then polarizers and hoods are recommended.

If you often shoot still life (yes, it is still life), or shoot night scenes, then use uv mirrors and tripods.

If you often shoot fireworks and starlight (it is estimated that novices should not have this purpose), then use a uv mirror, tripod and line player.

If you often shoot indoors (such as weddings, at home) or often shoot people, then uv mirrors, as for soft light screens, are recommended. When advanced, you can buy flash and soft light cover.

As for batteries, chargers, card readers and the like, I won't say much. You can't live without them.
