The Python program that prompts the user to enter 20 numbers and calculates the sum of the positive ones:
def main():
num_count = 20

In this program, we define a function main() that runs the main logic.
It uses a for loop to prompt the user to enter 20 numbers.
Each input is converted to a floating-point number using float(), and if the number is positive (greater than 0), it adds it to the positive_sum variable.
The program then prints the sum of the positive numbers after all inputs are processed.
