I saw 16 thumbs-down out of 24_367 views and suspected you had forgotten the warning message we all see at the end. I now have got to the end and suspect the malcontents never bothered to finish the video. It is a good introduction.

so, as far as I understand, eval() is basically a combination of int( ), and float( ).
Well in that case, I know both int( ) and float( ) have their uses, but usually its better just to use eval( ), as it takes out the possibility of making an error, right?

What would this print out if you entered "print(eval(3.0))"?
Will it recognize this is a 3 and an int or will it see that it has a .0 in the end and say it is a float?
