Lists differ from strings in two ways; one way is that it's mutable, the other way is that the values need not be characters. They can be numbers, they can be characters, they can be strings they can even be other lists.

有两个不同之处，一个在于数组是可变的;,另一点在于数组里面的值，不一定是字符,可以是数，可以是字符,也可以是字符串,甚至可以是其他的数组。

And again, this is between the p orbitals, these are not hybrid orbitals, so when we name this bond we're going to name it as a pi bond here, because it's between two p orbitals, and it's going to be between the carbon 2 p y orbital, and the other carbon 2 p y orbital.

同样，这是在p轨道之间的，它们不是杂化轨道，所以当我们命名这个键时,我们要命名它为π键，因为它在两个p轨道之间，而且是在碳2py轨道，和另一个碳2py轨道之间。
