How to put values of a list into a string

Question

I am trying to place several values from a list into a string. The code I have is below:

ID = [0, 1, 2]
print 'ID {0}, {1}, and {2}.'.format(ID)

or

print (r'(ID\s*=\s*)(\S+)').format(ID)

This does not work. Does anyone know where I'm going wrong. The code in the second line prints out the list:

[0, 1, 2]

the first line says:

File "tset.py", line 39, in b
    print 'ID {0}, {1}, and {2}.'.format(ID)
IndexError: tuple index out of range

Thanks

oh, dear. Look, your second addition has almost no relation to the question originally asked. Please remove it and ask a new question. And you'll need to include proper formatted, full code and not some random pieces. — SilentGhost

You have to unpack the list.

ID = [0, 1, 2]
print 'ID {0}, {1}, and {2}.'.format(*ID)

>>> 'ID {0}, {1}, and {2}.'.format(*ID)
'ID 0, 1, and 2.'

You need to unpack your list.

Your second code doesn't make much sense.
