Create a program called countVowels.py that has a function that takes in a string and then prints the number of unique vowels in the string (regardless of it being upper or lower case). Data Eastern University eiOuayOI   in python and using the sys.argv - I can get one at a time, but not all three correctly. Not sure how to fully use the sys.argv function.

Write a Python function that takes a string as parameter. The string has only the digits 0-10 as characters and its length is divisible by 3. string is not empty. You need to create two new strings. For this, you can use a for loop with a step of 3 (step = 3) to step through the string in blocks of 3 characters. Create the first string where each character is the first character of each block of 3 characters. Create the second string where each 2 characters are the second and third characters of each 3 character block of s.

Using Python: The function takes a string (ex: '..^<>..vv'), an integer n, width, height, and depth as inputs. Returns the n'th part of the string.  I am very confused on how to incoporate the depth into this problem (i.e. making it 3D instead of 2D).

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.

Implement a Program that compresses strings in a simple way by counting repeated characters. The string aabcccccaa, for instance, would become a2blc5a3. Your function should return the original string if the "compressed" string did not end up being any smaller than the original string. You can assume that the string only contains characters in upper- and lowercase (a–z).

Write the algorithm in a flow chart. The arithmetic operations are limited to only addition, subtraction, multiplication, and division. You can use chart software such as Lucidchart, powerpoint, or Visio. Please export it to a pdf file (e.g., Q3.pdf) Implement the algorithm in C. Again the arithmetic operations are limited to only addition, subtraction, multiplication (in Q3 not in Q4), and division (in Q4 not in Q3). (e.g., Q3.c) Implement the algorithm for MARIE architecture (e.g., Q3_MARIE.mas) The numbers of instructions in Q3_INSTRS.docx (Word document) Q4. Logarithm (Iterative algorithm) - Use Q2   Get a user input of two positive integer numbers: A and B where A is a base and B is an exponent of A Calculate C= Log base A of B Print C   Test case: A=2, B=16 Output should be 4

Write a function named encode_string(sentence) that takes a string value as its input and returns an encoded string, where each character of the input string is replaced by its ASCII code plus 3 values. Whitespace characters should not be encoded. For example, if the function was passed the input string: Hello World then it should return: Khoor Zruog For example: Test sentence "Hello World" print (encode_string(sentence)) Result Khoor Zruog
