US states named tuple (Python)

Now here is a brain teaser, list all the states that joined the Union after 1865.

Now here is a brain teaser, list all the states that joined the Union after 1865

Add the following to the end:

print('-'*35)

print("US states admitted after 1865:")
for state in instance_list:
    if int(state.date[-4:]) > 1865:
        print("{:15} {}".format(state.state, state.date[-4:]))

Works for me ...

Oops, the output is:

    -----------------------------------
    US states admitted after 1865:
    Alaska          1959
    Arizona         1912
    Colorado        1876
    Hawaii          1959
    Idaho           1890
    Montana         1889
    Nebraska        1867
    New Mexico      1912
    North Dakota    1889
    Oklahoma        1907
    South Dakota    1889
    Utah            1896
    Washington      1889
    Wyoming         1890
