Thank you much appreciated

The fast F/1.8 aperture will help in low light. It will also focus faster than the kit lens since the lens aperture is wider than the kit lens. Most of the EF-S 18-55mm kit lenses have a variable aperture of F/3.5-5.6 or the latest STM version F/4-5.6. Which doesn't help in low light or low contrast situations.

So if i have it one shot i wont have to turn the focus ring

The lens will autofocus normally. If you want to manually override AF. You have to half press the shutter button and turn the focus ring. If you want to use what Canon calls Full Time Manual Focus or Manual Focus Override. Not ALL lenses support this feature. All STM lenses support this feature. If the lens doesn't say STM or USM (there are some lenses that don't support it) in the name it doesn't support it. Also Ring Type and Nano USM lenses also support it. Most Ring Type USM lenses don't require a half press of the shutter button for Full Time Manual Focus. They use a clutch under the focus ring to provide Full Time Manual Focus mechanically instead of electrically. Some Ring Type USM lenses such as the EF 85mm F/1.2L II USM lens provides Manual Focus Override electrically like an STM lens does. Also Nano USM provides Manual Focus Override electrically too. Canon used to use a cheaper USM AF motor called Micro Motor USM. These lenses DO NOT provide Full Time Manual Focus so NEVER turn the focus ring without switching the lens to MF first. This AF motor was discontinued years ago and replaced by Nano USM. The only lens that provides Manual Focus Override with a Micro Motor USM AF motor is the EF 50mm F/1.4 USM lens.

You can USE this lens, but do you WANT to?  On your crop-sensor T7 it will give the effect of an 80mm lens on a full-frame body. This is into telephoto range. 

If you want something more "normal" in field of view, the EF-S 24mm f/2.8 STM would be more suitable. Or an EF-S 18-55  f/4-5.6 STM for a basic versatile zoom lens.

This my first camera bro i don't know anything about anything

"This my first camera bro i don't know anything about anything"

OK that's fine we were al there once. Some advice is better and more helpful then others. The bottom line is if you see this in the name of the lens it will work. "To simplify any lens with "EF or EF-S" in its name can be used."

Now a little history, once upon a time most all cameras came with a 50mm lens as standard. And at the time zooms were not the best they could be. But today zooms are as good and some are better than primes lenses such as the 50mm. So today the trend is to have a zoom lens as the standard lens. It is way more easy to use and friendly. If you have a 50mm lens and it has EF or EF-S in it name such as Canon EF 50mm f/1.8 STM Lens, it will work just fine. Your photos will look exactly like what you see in the view finder or LCD screen. Pay no attention to anything else.
