講英文卡住怎麼辦？學會這5句保證救援成功

常聽見老外和老外之間的談話，沒聽清楚就問對方Pardon? 而我們如果沒聽清楚、沒聽懂別人的英文，就會開始怪自己差，搞得人人有種英語原罪似的。沒想到、講不出來，在溝通中是很正常的事，去掉英文的罪惡感，是英文進步的第一步。一時想不起，直接說，不要支支吾吾。怎麼直接說呢？
1.It's on the tip of my tongue...（話就在我嘴邊，什麼來著......）tongue是舌頭，tip是尖端，tip of my tongue多傳神的畫面，就要想起來，但吐不出來。
2.How shall I put it?（我該怎麼說好呢？）有時候是沒想到，不知怎麼措辭，可以用這句；有時候是別人問你一個問題，你不必直接給答案，理一下思緒，就用How shall I put it?
3.What's the word for it...（這個怎麼說來著......）剛好卡在一個單字，就用這句，停頓一下，旁邊如果有懂了的人，就會幫你補上這個字。
4.Now, let me see.（讓我想想。）講到一半找不到字，直接說Now, let me see.對話中停下來想想，讓對方適時插入也會讓對話更豐富。
5. Now, where was I?（我剛說到哪兒了？）老美說話中斷之後，要繼續話題，卻忘了說到哪裏，常會自言自語說：Now, where was I? Oh, yes（嗯，我剛才談到哪裏？啊，想起來了。）
有時候沒想起，你的聽眾就會幫你補充訊息，注意是where was I，用過去式動詞，要幫人補充的話，就用過去進行式。例如：
A: Now, where was I ?
B: You were telling me about your travels in Europe.

difference between two strings in python

import difflib

s1 = "abcdefghijklmnop"
s2 = "abcdefghi"
s = difflib.SequenceMatcher(a=s1, b=s2)
for block in s.get_matching_blocks():
    print "match at a[%d] and b[%d] of length %d" % block

Python sort dic by keys, values. sort list

Python dict sort keys, values

>>>numbers = {'first': 1, 'second': 2, 'third': 3, 'Fourth': 4}
>>> [key for key in sorted(numbers.keys())]
['Fourth', 'first', 'second', 'third']
>>> [value for value  in sorted(numbers.values())]
[1, 2, 3, 4]

#################################################

sort by key:
>>> dic={'hello': 1, 'aa': 2,'b':3}
>>> sorted(dic.items())
[('aa', 2), ('b', 3), ('hello', 1)]
------

>>> sorted(dic.items(),key=itemgetter(0))

sort by values:
>>> dic={'hello': 1, 'aa': 2,'b':3}
>>> sorted( dic.items(), key= lambda x:x[1] )    #dic.items()取出了x=[key,value]，sort 是用x[1]
[('hello', 1), ('aa', 2), ('b', 3)]
>>> sorted(dic.items(),key=lambda x:x[1],reverse=True)
[('b', 3), ('aa', 2), ('hello', 1)]
------
>>> sorted(dic.items(),key=itemgetter(1))

##################################################

>>> students = [('john', 'A', 15), ('jane', 'B', 12), ('dave', 'B', 10),]

用 operator 函数来加快速度, 上面排序等价于:(itemgetter的用法)
>>> from operator import itemgetter, attrgetter
>>> sorted(students, key=itemgetter(2))

用 operator 函数进行多级排序
>>> sorted(students, key=itemgetter(1,2))  # sort by grade then by age
[('john', 'A', 15), ('dave', 'B', 10), ('jane', 'B', 12)]
