In this unit, you used this code to ensure that the user would enter a number and not letters: while True:

try:

num = int(input("Enter your age: "))

break

except ValueError:

print("That's not a number!")

How could you modify this code to be sure that the user enters a positive number?

What is added to the < meta > tag to describe the encoding type?

Agood flowchart alludes to both the inputs and outputs you will need to receive and give to the user. true or false?

Suppose you have 9 coins and one of them is heavier than others. other 8 coins weight equally. you are also given a balance. develop and algorithm to determine the heavy coin using only two measurements with the of the balance. clearly write your algorithm in the form of a pseudocode using the similar notation that we have used in the class to represent sorting algorithms
