So, again, we first tokenize the string into words or sentences. Then use the len() function to find the number of words or sentences in the string. How to Find the Number of Words in a String We first find the number of words in a string. This requires us to tokeni...

如果想在一个字符串中从前向后查找有没有另外一个字符串,可以使用字符串的find或index方法。在使用find和index方法时还可以通过方法的参数来指定查找的范围,也就是查找不必从索引为0的位置开始。 s = 'hello, world!' print(s.find('or')) # 8 print(s.find('or', 9)) # -1 print(s.find('of')...
