Write a Python program to take a string from user and remove all the duplicate characters from it where the order does not required to be same.

Using Python, use import sys Create a program, longest.py, that has a function that takes one string argument and prints a sentence indicating the longest word in that string. If there is more than one word print only the first.  Your print statement should read:               The longest word is x               Where x = the longest word.  The word should be all lowercase.

Write a python program where you will be given a string that contains multiple sentences separated by a comma. Your task is to separate the vowels and consonants in each word of each sentence and put the consonants at the start of the word and the vowels at the end and when doing so you have to ignore repeating vowels and consonants in a specific word. Sample Input 1: "Hello there, I will have tea, General Kenobi, I will be back" Sample Input 2: "Go go power rangers, There is no place like home, You have got a friend in me" Sample output 1: Hleo thre, I wli hvae tea, Gnrlea Knbeoi, I wli be bcka Sample Output 2: Go go pwroe rngsae, Thre si no plcae Ikie hmoe, You hvae gto a frndie ni me

IN PYTHON: Given a string representing a 10-digit phone number, output the area code, prefix, and line number using the format (800) 555-1212. Ex: If the input is: 8005551212 the output is: (800) 555-1212  Hint: Use string slicing operators. 18005551212 is not allowed.

In Python use import sys Create a program that has a function that takes in an argument and prints the number of vowels in the string. It should work for both lowercase and uppercase vowels.
