USING THE SPLIT() FUNCTION TO COMPARE WORDS

Listing 2.4 shows the content of Compare2.py, which illustrates how to use the split() function to compare each word in a text string with another word.

Listing 2.4: Compare2.py

x = 'This is a string that contains abc and Abc'

y = 'abc'

identical = 0

casematch = 0

for w in x.split():

 if(w == y):

  identical = identical + 1

 elif (w.lower() == y.lower()):

  casematch = casematch + 1

if(identical > 0):

 print('found identical matches:', identical)

if(casematch > 0):

 print('found case matches:', casematch)

if(casematch == 0 and identical == 0):

 print('no matches found')

Listing 2.4 uses the split() function to compare each word in the string x with the word abc. If there is an exact match, the variable identical is incremented. If a match does not occur, a case-insensitive match of the current word is performed with the...
