The simplest way:
最简单的方法：
new_string = str1 + "\n" + str2
回答by Michael Laszlo
You can use the concatenation operator, +:
您可以使用连接运算符+：
str3 = str1 + '\n' + str2
Or you can use the joinmethod on your delimiter, '\n':
或者您可以join在分隔符上使用该方法'\n'：
str3 = '\n'.join([str1, str2])
The latter approach works well when you have a bunch of strings in an array.
当数组中有一堆字符串时，后一种方法效果很好。
lines = ['A Story', 'by Me', '', 'An aardvark escaped from the zoo.', '', 'The End']
story = '\n'.join(lines)
print(story)
