You can use the concatenation operator, +
:
str3 = str1 + '
' + str2
Or you can use the join
method on your delimiter, '
'
:
str3 = '
'.join([str1, str2])
The latter approach works well when you have a bunch of strings in an array.
lines = ['A Story', 'by Me', '', 'An aardvark escaped from the zoo.', '', 'The End']
story = '
'.join(lines)
print(story)
