语法错误列表/字典

Question

Python 3: someList = [0000, 1000, 0100]#, 1100, 0010, 1010, 0110, 1110, 0001, 1001, 0101, 1101, 0011, 1011, 0111, 1111]

have a list which gives me a syntax error if I put more than 2 items in the list

someList = [0000, 1000] works but if I add anymore it keeps giving me an error

Answer 1

Using the same list, I get a syntax error in Python 3 on your number "0100", not because it is the third item, but rather, due to the value itself. I also get a syntax error just doing

someList = []
someList.append(0100)

So really it seems to be the value causing the problem. I'm not sure exactly what you are trying to do, but if you just want binary literals in a list, you can use something like this:

someList = [0b0000, 0b1000, 0b0100, 0b1100, 0b0010, 0b1010, 0b0110, 0b1110, 0b0001, 0b1001, 0b0101, 0b1101, 0b0011, 0b1011, 0b0111, 0b1111]

..where the "0b" prefix (that's zero b) represents a binary number.
