#WAP to print a string and the number of vowels present in it

### Source Code and Execution of Program

st=input(“Enter the string”) #enter the string which you want to show and calculate vowels.
print(“Entered string =”,st) # The input string is shown as output
st=st.lower() #the string is lower casse and save in st
c=0 #vowel counter is set to zero
v=[‘a’,’e’,’i’,’o’,’u’] # vowels are these numbers a,e,i,o,u
for i in st: # for loop from starting of string to the last iteration with last character of string.
if i in v: #it checks whether the character is same as in v.
c+=1 #the characters increases in value 1,2,3 if character is a vowel.
print(“Number of vowels in entered string =”,c) Then the number of vowel string is shown with the number of vowel

### Output of Printing a string and number of vowels in Python

Here we have given input string as – It is a good view of waterfall.
It first shows the string typed as output. Then calculate the number of vowels. which is 11.
Similarly the next string this way you look more beautiful is printed and the vowels are calculated which is 13.
