Python program to accept the strings which contains all vowels
Sometimes you want to accept input based on certain conditions. Here, we are going to see the same type of program. We will write a program that allows only words with vowels. We will show them whether the input is valid or not.
Let's see the approach step by step.
Define a list of vowels [A, E, I, O, U, a, e, i, o, u]
Initialize a word or sentence.
Iterate over the word or sentence.
Check if it is present in the list or not.
3.1.1. If not, break the loop and print Not accepted.
- Else print accepted
Example
Let's convert the text into Python code.
def check_vowels(string):
# vowels
vowels = ['A', 'E', 'I', 'O', 'U', 'a', 'e', 'i', 'o', 'u']
# iterating over the string
for char in string:
if char not in vowels:
print(f"{string}: Not accepted")
break
else:
print(f"{string}: Accepted")
if __name__ == '__main__':
# initializing strings
string_1 = "tutorialspoint"
string_2 = "AEiouaieeu"
# checking the strings
check_vowels(string_1)
check_vowels(string_2)Output
If you run the above code, you will get the following results.
tutorialspoint: Not accepted AEiouaieeu: Accepted
Conclusion
You check different properties based on your requirements. If you have any doubts in the tutorial, mention them in the comment section.
