Answer 1

Have a look at the below code. I have put comments wherever required for better understanding.

Question 9:

Question 11:

Question 12:

Question 13:

pi = 3.14159 
formatted = "${:.2f}".format(pi) # format the value
print("Pi day sale! All pies", formatted, "off.")

total = 0 

while True:
    ans = input("Enter a number or nothing when done:")
    if (ans==""):
        break
    total = total + float(ans)
    
print("The total is",total)

while True:
    x = int(input("Enter a positive single digit integer:"))
    if x not in range(1,10):
        break
print("You chose", x)

temp = int(input("Enter the tempearture: "))
if temp>=88:
       print("Hot")
elif temp in range(56,88):
       print("Fair")
else:
      print("Cold")
