Question

I am using Python2.7 and I would like to loop through a list x times.

a=['string1','string2','string3','string4','string5']
for item in a:
  print item

The above code will print all five items in the list, What if I just want to print the first 3 items? I searched over the internet but couldn’t find an answer, it seems that xrange() will do the trick, but I can’t figure out how.

Thanks for your help!

Answer 1

Sequence Slicing is what you are looking for. In this case, you need to slice the sequence to the first three elements to get them printed.

a=['string1','string2','string3','string4','string5']
for item in a[:3]:
      print item

Even, you don’t need to loop over the sequence, just join it with a newline and print it

print '\n'.join(a[:3])
