as title says i simply need to add a . before each letter in my string while having vowels removed and making it lowercase i got it working just cant add the .s there here is my code
s = str(input())
vowels = ('a','e','o','u','i','A','E','O','U','I')
for letter in s:
if letter in vowels:
s = s.replace(letter,'').replace()
print(s)
Use:
s = input()
vowels = set('aeoui')
print(''.join([f'.{x}' for x in s.lower() if x not in vowels]))
Sample run :
Hello
.h.l.l
All other answers will insert a .
in front of every character in the string, but you specified that you want letters only. So I am assuming that you only want az
to be prepended with a .
for which I suggest re.sub
:
import re
s = "This is some test string. It contains some symbols also ()!!"
result = re.sub('[aeoui]', '', s.lower()) # remove vowels and make lowercase
result = re.sub("([a-z])", r".\1", result) # prepend '.' to every letter
print(result)
Outputs:
.t.h.s .s .s.m .t.s.t .s.t.r.n.g. .t .c.n.t.n.s .s.m .s.y.m.b.l.s .l.s ()!!
You can do it step by step:
Replace all the vowels in the string with ''
for i in s:
for j in vowels:
s=s.replace(j,'')
Convert the string into lowercase:
s=s.lower()
Adding '.' in between each letters:
s='.' + '.'.join(s)
