Print vowels in a string in python

02.02.2021 Comments

Hi, in this tutorial, we are going to write a program that counts the number of vowels in the user input string using for loop in Python. So, declare a variable count and initialize to 0 which keeps the track of vowel count. Now before counting the vowels, first make sure the string is completely lowercase because we are checking vowels from the list where we declared vowel in lowercase only. So keep it in mind to the first convert string to lowercase and for that, we are going to use lower function of Python.

So, we have converted the string to lowercase, now traverse through the string and compare each character of string in the list of vowels whether the character is present in the list or not. If the character is present in the list, then we simply increment the count variable by 1 otherwise continue to the loop without incrementing the count variable.

And at last, after traversing through the string, return the count variable back to the function call. Now, we have defined the Count Vowel function above which calculates the count of the number of vowels in the string.

So after this, ask the user to enter string which needs to pass to this above function and then print the count for the vowel.

Approach: 1. Create a set of vowels using set and initialize a count variable to 0. Traverse through the alphabets in the string and check if the letter in the string is present in set vowel. If it is present, the vowel count is incremented. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.

print vowels in a string in python

This can be done using various methods. In this article, we will go through few of the popular methods to do this in an efficient manner. In this method, we will store all the vowels in a string and then pick every character from the enquired string and check whether it is in the vowel string or not. The vowel string consists of all the vowels with both cases since we are not ignoring the cases here.

If the vowel is encountered then count gets incremented and stored in a list and finally printed. This also performs the same task but in a different way. In this method, we form a dictionary with the vowels and increment them when a vowel is encountered. In this method, we use the case fold method to ignore the cases, following which we form a dictionary of vowels with the key as a vowel.

This is a better and efficient way to check and find the number of each vowel present in a string. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.

Chinmoy Lenka.To remove all vowels present in a string in python, you have to ask from user to enter a string and start removing all vowels from it. After removing all vowels from that string, print the final string without any vowel as output as shown in the program given below. Following python program ask from user to enter any string to remove all vowels from that string and then prints that string without any vowel:.

Here is the sample run of the above python program to illustrates how to remove all vowels from a string:. Above one is the initial output produced after running the program, now you have to supply or enter any string say codescracker that contains some vowels oeae to remove all the containing vowels from that given string and print the same string back on output screen but without any vowels, that will be cdscrckr :.

Did I not understand the instructions correctly or what's wrong with my code? Hi there! The reason the code in the original answer posted here worked and your code doesn't is that your code doesn't take into account what happens when you remove an item.

Let's say that you are at index 2 and you remove that item. The item in index 3 moves down to the 2 place, and the 4 moves down to the 3 place. But your next iteration, you'll be looking at what's in place 3. So essentially, you are skipping a check on a letter. What will be returned is "trhuse". Essentially, using the remove function messes up where the function is currently looking as far as index. Hope this helps! For anyone reading this thread, please note that an answer was originally given here with working code.

The question then became why that solution worked and this solution does not. This answer is an attempt to explain the results. As Jennifer Nordell mentioned it messes up the indexing and causes skipped iterable elements. Better to use a description of what the list contains, such as, "letters". This leads to the more readable:. Thanks Jennifer and Chris! I have a little of a hard time understanding why the script works if there are two vowels in a row and they're the same vowel, but not if there are different vowels in a row.

I will, however, keep in mind not to mess with the iterable of a for loop First, I'd like to thank you for convincing me to dive further into the mutation of iterables than I was ever inclined to do And I have an alternate version of your code here, which I hope can help explain better what's going on.

It's not that the two e's are together, but rather two vowels together, and I'll try to explain as best I can. I apologize for the length of this reply. Bottom line is that in this case some checks are skipped entirely. We have five instances of the letter "e", but only four checks for the letter "e".

The thing removed is always the first occurrence of that object inside the list. The pattern here is the character after a removed letter is skipped because the indexes are shifted by one on each letter removal.
