[英]Python - Regular Expression find position of first vowel in a string
How to use regular expression to find the position of first vowel in a string? 如何使用正则表达式查找字符串中第一个元音的位置?
eg string = 'this is the day!' 例如string ='今天是一天! 'i' is the first vowel and I want to have the position 2 (since i is the 3rd element in the string) “ i”是第一个元音,并且我想拥有位置2(因为i是字符串中的第三个元素)
What is I want to find the 2nd vowel, the 3rd, etc.? 我想找到第二个元音,第三个元音等等?
您不需要正则表达式,可以通过一个简单的列表理解来完成,位置为1
vowel_pos = [ i for i,v in enumerate(my_string) if v.lower() in ('a','e','i','o','u','y') ]
