假设我们有一个“字符串”和“单词”,我们需要使用python查找该单词在字符串中的出现次数。这就是我们在本节中要执行的操作,计算给定字符串中的单词数并打印出来。
计算给定字符串中的单词数
#方法1:使用for循环
test_stirng = input("要搜索的字符串是: ") total = 1 for i in range(len(test_stirng)): if(test_stirng[i] == ' ' or test_stirng == '\n' or test_stirng == '\t'): total = total + 1 print("Total Number of Words in our input string is: ", total)
要搜索的字符串是: Python is a high level language. Python is interpreted language. Python is general-purpose programming language Total Number of Words in our input string is: 16
test_stirng = input("要搜索的字符串是: ") total = 1 i = 0 while(i < len(test_stirng)): if(test_stirng[i] == ' ' or test_stirng == '\n' or test_stirng == '\t'): total = total + 1 i +=1 print("Total Number of Words in our input string is: ", total)
要搜索的字符串是: Python is a high level language. Python is interpreted language. Python is general-purpose programming language Total Number of Words in our input string is: 16
def Count_words(test_string): word_count = 1 for i in range(len(test_string)): if(test_string[i] == ' ' or test_string == '\n' or test_string == '\t'): word_count += 1 return word_count test_string = input("要搜索的字符串是:") total = Count_words(test_string) print("Total Number of Words in our input string is: ", total)
要搜索的字符串是:Python is a high level language. Python is interpreted language. Python is general-purpose programming language Total Number of Words in our input string is: 16
上面也有其他几种方法,可以找到用户输入的字符串中的单词数。
