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.
