Loops and Strings in python -

given strings s1 , s2, not of same length. create new string consisting of alternating characters of s1 , s2 (that is, first character of s1 followed first character of s2, followed second character of s1, followed second character of s2, , on.

once end of either string reached, remainder of longer string added end of new string. example, if s1 contained "abc" , s2 contained "uvwxyz", new string should contain "aubvcwxyz". associate new string variable s3.

my attempt is:

s3 = ''  = 0  while < len(s1) , < len(s2):      s3 += s1[i] + s2[i]      += 1      if len(s1) > len(s2):          s3 += s1[i:]      elif len(s2) > len(s1):          s3 += s2[i:] 

s1 = "abcdefg" s2 = "hijk" s3 = "" minlen = min(len(s1), len(s2))     x in range(minlen):     out += s1[x]     out += s2[x] out += s1[minlen:] print out 

a couple of things keep in mind. first, can treat python string array, , can access item @ given index using brackets. also, second last line makes use of splicing, more information, see how can splice string?
