Given a text (paragraph) and a word whose occurrence to be found in the text/paragraph, we have to find the how many times word is repeated in the text.

給定一個文本 (段落)，其出現在文本/段落被找到的單詞 ，我們必須找到如何詞多次在文本重復。

Example:

例：

    Input:
text = "this is a book, this is very popular"
word = "this"
Output:
'this' found 2 times.

Consider the below program implemented for counting occurrences of just one word in a text.

考慮下面的程序，該程序用于計數文本中僅一個單詞的出現 。

Program:

程序：

# Python program to count occurrence 
# of a word in text
# paragraph
text = """Lorem Ipsum is simply dummy text of the 
printing and typesetting industry. Lorem Ipsum has been 
the industry's standard dummy text ever since the 1500s"""
word = "text"
# searching word
count = 0
for w in text.split():
if w == word:
count = count + 1
# printing result
print("\'%s\' found %d times." %(word, count))
word = "is"
# searching word
count = 0
for w in text.split():
if w == word:
count = count + 1
# printing result
print("\'%s\' found %d times." %(word, count))
word = "Hello"
# searching word
count = 0
for w in text.split():
if w == word:
count = count + 1
# printing result
print("\'%s\' found %d times." %(word, count))

Output

輸出量

'text' found 2 times.
'is' found 1 times.
'Hello' found 0 times.
