答案很可能是面对着我......

Answer 1

使用str.partition或str.rpartition：

>>> s = "aaa About DoctorTardi this Stats for Project Ares bbb"
>>> head, sep1, x = s.partition("About DoctorTardi")
>>> _, sep2, tail = x.partition("Stats for Project Ares")
>>> head + sep1 + sep2 + tail
'aaa About DoctorTardiStats for Project Ares bbb'

Answer 2

   def remake_string(initialString, startPhrase, endPhrase):

       startingIndex = initialString.rfind(startPhrase)e #finds the highest index of the phrase
       endingIndex = initialString.find(endPhrase)# finds the lowest index of the phrase
       newString = initialString[:startingIndex] + initialString[endingIndex:] ''' 
       removes everything in the midding by starting getting everything up to the end of 
       the startPhrase and adding it to from the endPhrase on '''

       return newString

Answer 3

x = "About DoctorTardi bla bla Stats for Project Ares"
x = x[:17]+x[25:]
print x

• x[:17]是x的子字符串，从开头到第17个字母。

• x[25:]是x的子字符串，从第25个字母到结尾。

• x[17:25]是x的子字符串，从第17个字母到第25个字母 信。
