知识点:

  1. 换行符

    \n:换行符

    例:字符串后面跟着\n 就是下一个字符串换行的意思。

months = "Jan\nFen\nMar\nApr\nMay\nJun\nJul\nAug"
print (months)

2. 多行注释符

“”“字符串内容”"" :主要体现在跨行的字符串上,会包含两个界定符号之间的所有字符,包括看得见和看不见的,例如回车换行等。

可以理解为在三个引号之间的字符串你是怎么输入的,打印时就如何输出,减少了\n这类的换行符。

注:两头的三个引号之间不能有空格。

例:

print ("""
    There's something going on here.
        With the three double-quotes.
            We'll be able to type as muchas we like.
                Even 4 line if wu want, or 5, or 6.
""")
