Find a character in a list of words

I am trying to find a specific character in a list of words and then print all the words that match. for example, I have a list of 6 words. I would like to find a way to select all the words with a ('.') (fullstop) in them and transfer them to another list.

Example: 

List ['alpha', 'bravo', 'charlie.', 'delta', 'echo']

I would like it to find Charlie and its position in the list

I mostly just need the if statement for it Thanks in advance!

This is what I have so far 

sent = str(input('enter sentance '))
words = sent.split()
print (words)

The usual way to know if a character is in a string in python is "in"

'.' in "charlie."

that will return True.

To know the position of an element in a list you can iterate using enumerate(list) and will return a pair of (index,value).

To get a list of the index and the strings who have '.' character you can do something like this:

[(pos, word) for pos, word in enumerate(list) if '.' in word]

Assume you have a list l = ['alpha', 'bravo', 'charlie.', 'delta', 'echo'] Then you can create a list with all words containing '.' in it by doing filter like below:

l = ['alpha', 'bravo', 'charlie.', 'delta', 'echo']
list_with_dot = [x for x in l if x.find('.') != -1]

If you want it without list comprehension:

sent = input('Enter sentence > ')
words = sent.split()
for word in words:
    if "." in word:
        print(word)

Also, you if you're in Python 2.7, use raw_input, input for Python 3.

you can try this (for python 2.7)

sent = raw_input('enter sentance ')


lista = ['alpha', 'bravo', 'charlie.', 'delta', 'echo']

res = [i for i in lista if (sent in i)][0]

print(str(res) + "is at index " + str(lista.index(res)))
