Python program to count number of occurrences of each word in string
In this tutorial, you will learn how to write a python program to count number of occurrences of each word in string. This is one of the step in text pre- processing. This step will help in data preparation for building models for machine leaning.
str_1 = 'Hi, How are you ? I am fine, What about you ?'
def count_words(str):
counts = {}
words = str.split()
for word in words:
if word in counts:
counts[word] += 1
else:
counts[word] = 1
return counts
print(count_words(str_1))
Output:
{'Hi,': 1, 'How': 1, 'are': 1, 'you': 2, '?': 2, 'I': 1, 'am': 1, 'fine,': 1, 'What': 1, 'about': 1}
