这是一个创建于 3536 天前的主题，其中的信息可能已经有所发展或是发生改变。
The len() function is used to count how many characters a string contains.
Get the first half of the string stored in the variable 'phrase'.
Note: Remember about type conversion.
phrase = """
It is a really long string
triple-quoted strings are used
to define multi-line strings
"""
first_half = ???????
print(first_half)
就是问？？？那里写什么，我一直没搞懂first_half指什么。

first_half = phrase[:len(phrase)]
我想是这样的 |

half嘛 就是一半 first half就是前面一半 所以len()/2 再切片就好 是不是我想得太简单了

phrase[0:len(phrase)//2]
截取前半部分，大概是这个意思吧 |

就是前半的意思，英语需要好好学习。
first_half = phrase[:len(phrase)//2]应该就编译通过了。 |
