   • Python | Tokenizing strings in list of strings

     Sometimes, while working with data, we need to perform the string tokenization of the strings that we might get as an input as list of strings. This has a usecase in many application of Machine Learning. Let’s discuss certain ways in which this can be done.

     Method #1 : Using list comprehension + split()

     We can achieve this particular task using list comprehension to traverse for each strings from list of strings and split function performs the task of tokenization.

     # Python3 code to demonstrate# Tokenizing strings in list of strings# using list comprehension + split() # initializing listtest_list = ['Geeks for Geeks', 'is', 'best computer science portal'] # printing original listprint("The original list : " + str(test_list)) # using list comprehension + split()# Tokenizing strings in list of stringsres = [sub.split() for sub in test_list] # print resultprint("The list after split of strings is : " + str(res))-

     The original list : [‘Geeks for Geeks’, ‘is’, ‘best computer science portal’] The list after split of strings is : [[‘Geeks’, ‘for’, ‘Geeks’], [‘is’], [‘best’, ‘computer’, ‘science’, ‘portal’]]

     Need to iterate through the tuple of test strings:

     a = 'test string'b = 'I am a cat'c = 'Washington'if any(s in test for test in (a,b,c) for s in ('this', 'test', 'cat')): print("found")

   • "IN" operator with empty strings in Python 3.0

     Top Answer

     Answered May 15, 2016 · 18 votes

     '' is the empty string, same as "". The empty string is a substring of every other string.

     When a and b are strings, the expression a in b checks that a is a substring of b. That is, the sequence of characters of a must exist in b; there must be an index i such that b[i:i+len(a)] == a. If a is empty, then any index i satisfies this condition.

     This does not mean that when you iterate over b, you will get a. Unlike other sequences, while every element produced by for a in b satisfies a in b, a in b does not imply that a will be produced by iterating over b.

     So '' in x and "" in x returns True for any string x:

     >>> '' in 'spam'True>>> "" in 'spam'True>>> "" in ''True>>> '' in ""True>>> '' in ''True>>> '' in ' ' True>>> "" in " "True

   • Strings and Dictionaries in Python

     Top Answer

     Answered Oct 26, 2013 · 2 votes

     With your two strings:

     alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"key = "XPMGTDHLYONZBWEARKJUFSCIQV"-

     Create a dictionary using zip()

     :

     mydict = {k:v for k, v in zip(alpha, key)} # Or dict(zip(alpha, key))

     Then in your encode() function, you can just do:

     def encode(plain): return ''.join([mydict.get(i, i) for i in plain])

     [mydict.get(i, i) for i in plain] Is equivalent to:

     newlist = []for i in plain: newlist.append(mydict.get(i, i))

     mydict.get(i, i)

     is equivalent to mydict[i], but if there is no key i, then i (the second parameter) is returned (instead of raising a KeyError)

     Note that the list will return something like ['M', 'X', 'U'], so the ''.join()

     will print it as 'MXU'
