Write function toAcronym which takes a string and make an acronym of it.

Rule of making acronym in this kata:

1. split string to words by space char
2. take every first letter from word in given string
3. uppercase it
4. join them toghether



Eg:


Code wars -> C, w -> C W -> CW

Difficulty: introductory

Starter code:

def to_acronym(input):
	

Solutions:
def to_acronym(input):
  # only call upper() once
  return ''.join(word[0] for word in input.split()).upper()

def to_acronym(input):
  return ''.join(w[0].upper() for w in input.split())

def to_acronym(input):
    return "".join(i[0].upper() for i in input.split())

def to_acronym(input):
    fstring = ""
    fstring += input[0].upper()
    for i in range(0, len(input)):
        if input[i] == " ":
            fstring += input[i+1].upper()
            
    return fstring
    pass

def to_acronym(i):
    return''.join(w[0]for w in i.split()).upper()

import re

def to_acronym(s):
    return ''.join(re.findall(r'\b(\w)', s)).upper()

import string
def to_acronym(input):
    return "".join([x[0].upper() for x in input.split(" ")])


to_acronym=lambda s:''.join(w[0]for w in s.split()).upper()

def to_acronym(input):
    words = input.split()
    acronym = ''
    for word in words:
        acronym += word[0]
    return acronym.upper()

def to_acronym(input):
