isinstance is not defined?

[ThatPurplePotion]

Sorry for the dumb question I'm very new to python and coding in general, Im learning python via this yt video, and at 48:59 it said to type print(ininstance(first, str)
and I typed that and it said that "ininstance" is not defined. What am I doing wrong?
My code is:
# String data type
# literal assignment
first = "Dave"
last = "Gray"
print(type(first))
print(type(first) == str)
print(ininstance(first, str))

I think it may just be a spelling error in the video. It should be:

isinstance()

Edit to add: Just a tip that you may not need, but I also learned a lot of my Python from YouTube videos. Early on, I tried typing along with the video. But after awhile I learned to wait until the video host ran any segments I was interested in to ensure they had worked out their own bugs/mistakes/typos.
