1. Count Letters
Write a function called unique_english_letters that takes the string word as a parameter. The function should return the total number of unique letters in the string. Uppercase and lowercase letters should be counted as different letters.
We’ve given you a list of every uppercase and lower case letter in the English alphabet. It will be helpful to include that list in your function.

#Write your function here
letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
def unique_english_letters(word):
counter = 0

if i in word:
counter += 1
return counter

3. Write a function named count_multi_char_x that takes a string named word and a string named x. This function should do the same thing as the count_char_x function you just wrote - it should return the number of times x appears in word. However, this time, make sure your function works when x is multiple characters long.

4. Check Name
Write a function called check_for_name that takes two strings as parameters named sentence and name.
