An archery target consists of a central circle of yellow surrounded by concentric rings of red, blue, black and white

 CODE :

An archery target consists of a central circle of yellow surrounded by concentric rings of red, blue, black and white. Each ring has the same width, which is the same as the radius of the yellow circle. Write a program called target.py that draws this target.

o Use a list of colors and a for loop to draw the target

o Hint: objects drawn later will appear on top of objects drawn earlier

o The output of the program should look like this:

Write a program that finds the average of a series of numbers entered by the user.

 Write a program that finds the average of a series of numbers entered by the user. As in the previous problem, the program will first ask the user how many numbers there are. Note: The average should always be a float, even if the user inputs are all ints.

CODE :

# sumnn.py 

def main() :

    n = int (input ("How many numbers are to be summed: ") ) 

    sum=0

    for i in range(n) :

Write a program to sum a series of numbers entered by the user.

 Write a program to sum a series of numbers entered by the user. The program should first prompt the user for how many numbers are to be summed. The program should then prompt the user for each of the numbers in turn and print out a total sum after all the numbers have been entered. Hint: Use an input statement in the body of the loop.

It Executes 5 times before quitting to convert Celsius temps into Fahrenhit

 Modify the convert.py program (Section 2.2) with a loop so that it executes 5 times before quitting. Each time through the loop, the program  should get another temperature from the user and print the converted value.

CODE :

#convert.py
