Program using re module that loops through the lines of a file or standard input where each line contains a single word and prints all words containing two adjacent vowels

Question

Example:

There is a list with ["eye", "ear", "waist", "neck"]

My output should be "ear" and "waist", since these words have two adjacent vowels in them.

Hey, @S,

you can have a look at the below given example:

s= "reading a book is great"

print(re.findall(r'\b\w[aeiou]{2}\w\b',s))

For both upper and lowercase vowels.

print(re.findall(r'\b\w[aeiouAEIOU]{2}\w\b',s))

You could use [A-Za-z] instead of \w, if you don't want a digit or _ exists before or after the vowels. Because \w also matches _ and digits.

print(re.findall(r'\b[A-Za-z][aeiouAEIOU]{2}[A-Za-z]\b',s))

Add case-insensitive modifier (?i) or re.IGNORECASE to do a case-insensitive match.

print(re.findall(r'(?i)\b[a-z][aeiou]{2}[a-z]\b',s))
