Python：对文本文件进行两次排序并拆分为不同的文件？

如何先按行长排序，然后按字母顺序排序，然后按行长拆分为单独的文件？ 我有这样一个单词列表文件：

a

actors

an

b

batter

but

我需要一个文件（1.txt，2.txt）为每行长度，每个字母排序。如何做到这一点

生成的文件应如下所示：

1.txt

2.txt

---

等等。

您可以将函数传递到sort中。类似于lambda，b：（len（a）应该这样做。

要补充前面的答案：

files = {}
for word in sort(words, lambda a,b: (len(a) < len(b)) if (len(a) != len(b)) else (a < b)):
    if len(word) not in files:    
         files[len(word)] = open("{0}.txt".format(len(word)), "w")
    files[len(word)].write("{0}\n".format(word))             

files={}
对于排序中的单词（单词，lambda，b:（len（a）

您可以这样做：

text = [x.strip() for x in """a

actors

an

b

batter

but""".splitlines() if x.strip()]

files = {}
for word in text:
    n = len(word)
    if n not in files:
        files[n] = open("%d.txt" % n, 'wt')
    files[n].write(word + "\n")

for file in files.itervalues():
    file.close()

“每行一个文件”是什么意思？1.txt和2.txt究竟应该包含什么？n.txt应该包含每行n个字符长的input.txt，按字母顺序排序。n.B.'前面的答案“可能会随着时间的推移而改变，因为大多数用户查看的答案都是按选票计数排序的。

files = {}
for word in sort(words, lambda a,b: (len(a) < len(b)) if (len(a) != len(b)) else (a < b)):
    if len(word) not in files:    
         files[len(word)] = open("{0}.txt".format(len(word)), "w")
    files[len(word)].write("{0}\n".format(word))             

text = [x.strip() for x in """a

actors

an

b

batter

but""".splitlines() if x.strip()]

files = {}
for word in text:
    n = len(word)
    if n not in files:
        files[n] = open("%d.txt" % n, 'wt')
    files[n].write(word + "\n")

for file in files.itervalues():
    file.close()
