# Define A function called Is_prime that takes a number x as input.
# for each number n from 2 to x-1, test if x is evenly divisible by N.
# If It is, return False.
# If None of them is, then return True.

# Define A function called reverse that takes a string Textand returns this string in reverse.
# for Example:reverse ("ABCD") should return "DCBA".
# You could not use the reversed or [:: -1] To help you with this.
# you could get a string containing special characters (for example,!, @, or #).

# Define A function called Anti_vowel that takes one string, text,
# as input and returns the text with all of the vowels removed.
# for Example:anti_vowel ("Hey you!") should return "Hy y!".
# Don ' t count Y as a vowel. Make sure to remove lowercase and uppercase vowels.
# import RE
# def Anti_vowel (str):
# Print (Re.sub (' [Aeiou] ', ', str))

# Define A function Scrabble_score that takes a string word as input
# and returns the equivalent Scrabble score for that word.
# assume your input is only one word containing no spaces or punctuation.
# As mentioned, no need to worry about score multipliers!
# Your function should work even if the letters you get is uppercase, lowercase, or a mix.
# Assume that you ' re only given non-empty strings.

# Write A function called Censor that takes the strings, text and Word, as input.
# It should return the text with the word to chose replaced with asterisks. For example:
# censor ("This hack is wack hack", "hack")
# should return:
# "This * * * * is wack * * * * *"
# assume your input strings won ' t contain punctuation or upper case letters.
# The number of asterisks you put should correspond to the number of letters in the censored word.

# Codecademy Python 5.11
# Define A function called count that have both arguments called sequence and item.
# Return the number of times the item occurs in the list.
# for Example:count ([1, 2, 1, 1], 1) should return 3 (because 1 appears 3 times in the list).
# There is a list method in Python so you can use for this, but you should does it the long method for practice.
# Your function should return an integer.
# The item you have input May is an integer, string, float, or even another list!
# is careful not to use list as a variable name in your code-it ' s a reserved word in python!
# def COUNT (Sequence,item):
# sum = 0
# for I in sequence:
# If I = = Item:
# sum+=1
# return sum

# Codecademy Python 5.12
# Define A function called purify that takes in a list of numbers,
# removes all odd numbers in the list, and returns the result.
# For example, purify ([]) should return [2].
# do not directly modify the list is given as input;
# instead, return a new list with only the even numbers.
# def purify (x):

# Codecademy Python 5.13
# Define A function called product that takes a list of integers as input and
# returns the product of the elements in the list.
# for Example:product ([4, 5, 5]) should return (because 4 * 5 * 5 is 100).
# Don ' t worry about the list being empty.
# Your function should return an integer.
# Def product (x):
# mul = 1

# Codecademy Python 5.14
# Write A function remove_duplicates that takes in a list and removes elements of the list is the same.
# for Example:remove_duplicates ([1, 1, 2, 2]) should return [1, 2].
# Don ' t remove every occurrence, since you need to keep a single occurrence of a number.
# The order in which your present your output does not matter.
# so returning [1, 2, 3] are the same as returning [3, 1, 2].
# do not modify the list to take as input! Instead, return a new list.

# Codecademy Python 5.15
# Write A function called Median that takes a list as an input
# and returns the median value of the list. For Example:median ([1, 1, 2]) should return 1.
# The list can be is of any size and the numbers is not guaranteed to is in any particular order. Make sure to sort it!
# If The list contains an even number of elements, your function should return the average of the middle.
