Python 程序来统计给定字符串中的单词数?
假设我们有一个“字符串”和一个“单词”,我们需要使用 python 在字符串中查找该单词出现的次数。这就是我们本节将要做的工作,统计给定字符串中的单词数并打印出来。
统计给定字符串中的单词数
方法 1:使用 for 循环
#方法 1:使用 for 循环
test_stirng = input("String to search is : ") 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)
结果
String to search is : 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
#方法 2:使用 while 循环
test_stirng = input("String to search is : ") 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)
结果
String to search is : 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
#方法 3:使用函数
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("String to search is :") total = Count_words(test_string) print("Total Number of Words in our input string is: ", total)
结果
String to search is :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
以上是其他两种查找用户输入字符串中的单词数的办法。
