Print and join statement in python

Question

I am newbie to python. I have a sequence and I am able to print it using join method and able to print the length of the sequence separately. I am not able to print

Answer 1

Yes I second @jonrsharpe str is buit-in and use should not use that name.

print " The join o/p is %s and The length is %s"%(s.join(seq),len(s.join(seq)))

Here your length is not 3 it will be 5. Since you have added 2 '-'. If you want to count excluding '-' then use line below.

print " The join o/p is %s and The length is %s"%(s.join(seq),len(s.join(seq).replace('-','')))

Answer 2

seq = ('a', 'b', 'c')
joined = '-'.join(seq)
print('The join output is:', joined, 'The length is:', len(seq))

or

print('The join output is: ' + joined + ' The length is: ' + str(len(seq)))

Answer 3

First of all, don't use str as a variable name. This is a built-in; using it as a variable name means you can't access it (e.g. to convert other items to strings).

Secondly, I would recommend string formatting here:

print "The join output is: {0}. The length is: {1}.".format("-".join(seq), 
                                                            len(seq))
