Python程序计算给定文本中单词的出现
给定一个文本（段落）和一个字，其出现在文本/段落被发现，我们必须找到多少次字的重复文本。
示例
Input:
text = "this is a book, this is very popular"
word = "this"
Output:
'this' found 2 times.考虑下面的程序，该程序用于计数文本中仅一个单词的出现。
程序：
#Python程序来计数发生
#文字中的一个词
#段
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"
#搜索词
count = 0
for w in text.split():
if w == word:
count = count + 1
#打印结果
print("\'%s\' found %d times." %(word, count))
word = "is"
#搜索词
count = 0
for w in text.split():
if w == word:
count = count + 1
#打印结果
print("\'%s\' found %d times." %(word, count))
word = "Hello"
#搜索词
count = 0
for w in text.split():
if w == word:
count = count + 1
#打印结果
print("\'%s\' found %d times." %(word, count))输出结果
'text' found 2 times. 'is' found 1 times. 'Hello' found 0 times.
