Write a Python program to demonstrate working of Replace duplicate Occurrence in String

Solution

test_str = 'Gfg is best . Gfg also has Classes now. Classes help understand better . '
print("The original string is : " + test_str) 
repl_dict = {'Gfg' : 'It', 'Classes' : 'They' } 
test_list = test_str.split(' ') 
res = ' '.join([repl_dict.get(val) if val in repl_dict.keys() and test_list.index(val) != idx 
                                else val for idx, val in enumerate(test_list)]) 
print("The string after replacing : " + res)
