上面有個(gè)地方缺了一個(gè)縮進(jìn)：from decimal import Decimal,ROUND_HALF_UP
def smart_round(x,n):
return str(Decimal(x).quantize(Decimal("0."+"0"*n),rounding=ROUND_HALF_UP))
def smart_round(x,n):
return str(Decimal(x).quantize(Decimal("0."+"0"*n),rounding=ROUND_HALF_UP))

python = 'Python'
a = A.format(s = short,p = python)
print(a)
B = 'Life {1} short,{2} need {0}'
b = B.format('Python','is','you')
print(b)
short = 'short'

實(shí)現(xiàn)任務(wù)最后一步輸出時(shí)可以這樣：print(round(s,2))，但是我第一次做的時(shí)候?qū)懗闪?，發(fā)現(xiàn)結(jié)果和2一樣，省略了末位的0，于是搜索了一下，要實(shí)現(xiàn)保留精確度到指定長(zhǎng)度，自建了一個(gè)函數(shù)，但對(duì)我這個(gè)入門級(jí)來說，這個(gè)函數(shù)我看不懂了，就先放著，以后看得懂了再來說說：
from decimal import Decimal,ROUND_HALF_UP
def smart_round(x,n):
return str(Decimal(x).quantize(Decimal("0."+"0"*n),rounding=ROUND_HALF_UP))
輸出時(shí)，round改為smart_round

def smart_round(x,n):
return str(Decimal(x).quantize(Decimal("0."+"0"*n),rounding=ROUND_HALF_UP))

這段代碼中“for b in S”是錯(cuò)誤的，因?yàn)樵谘h(huán)中修改了集合S的大小，導(dǎo)致了迭代器的大小發(fā)生了變化，從而引發(fā)了錯(cuò)誤。
