string formatter for tuple

[jeremito]

I have the following in my code

a = (1,2,3)
print "a = %s" %a

But when I run this, I get:

TypeError: not all arguments converted during string formatting

Now I realize why this happens, a is actually 3 elements when the print
statement is only expecting to print one value. I tried

print "a = %s" %(a)

but I got the same error.

How can I print a tuple with a single string format?
Thanks,
Jeremy

You can try

print "a = %s" % str(a)

or

print "a = %s" % repr(a)

which should both do the trick.

Try

print "a = %s" % (a, )

The exception to the "a single object can be formatted as a single
argument rather than a tuple" rule is when that single object is itself
a tuple!

Put the tuple in a tuple:

print 'a = %s" % (a,)

And remember: not the parenthesis create a tuple but the comma!

Tim print "a = %s" % str(a)
Timor
Tim print "a = %s" % repr(a)

Or wrap the tuple in a tuple:

print "a = %s" % (a,)

Skip
