Learning Python

OK, any tech geeks out there? I'm learning Python and this is giving me problems: Spot the error in the following python statement:

U2_albums = {
    "Boy": 1980,
    "October": 1982,
    "WAR": 1983,
    "The unforgettable Fire": 1984,
    "The Joshua Tree": 1987,
    "Rattle and hum": 1988,
    "Achtung Baby": 1991,
    "Zooropa": 1993,
    "Passengers:OST1": 1995,
    "POP": 1997,
    "All That You Can't Leave Behind": 2000,
    "How to dismantle an atomic bomb": 2004,
    "No line on the Horizon": 2009,
    "Songs of Innocence": 2014,
    "Songs of Experience": 2017
}

Syntax error: Invalid dictionary value


Any ideas?

Passengers has ceased to be.

Passengers has ceased to be.

Hmmm. OK, I'll try to run the code without it.

U2_albums = {
    "Boy": 1980,
    "October": 1982,
    "WAR": 1983,
    "The unforgettable Fire": 1984,
    "The Joshua Tree": 1987,
    "Rattle and hum": 1988,
    "Achtung Baby": 1991,
    "Zooropa": 1993,
    # "Passengers:OST1": 1995,
    "POP": 1997,
    "All That You Can't Leave Behind": 2000,
    "How to dismantle an atomic bomb": 2004,
    "No line on the Horizon": 2009,
    "Songs of Innocence": 2014,
    "Songs of Experience": 2017
}


Yup, I commented out Passengers and I'm all good to go.
