write a python function that counts the number of positive factors of a positive integer

Sure, here's a Python function that counts the number of positive factors of a positive integer:

def count_factors(n):
    count = 0
    for i in range(1, n+1):
        if n % i == 0:
            count += 1
    return count

You can use this function by calling it with a positive integer as an argument, like this:

count_factors(12)  # Returns 6, since 12 has 6 positive factors: 1, 2, 3, 4, 6, and 12
count_factors(7)  # Returns 2, since 7 has 2 positive factors: 1 and 7

Write a program that asks a string to the user, and counts the number of time each character occurs in the string，output is a set

Sure, I can help you with that! Here's a Python program that does what you're asking for:

string = input("Please enter a string: ")
count = {}

for char in string:
    if char in count:
        count[char] += 1
    else:
        count[char] = 1

print("Character count:")
for char, num in count.items():
    print(char, num)

This program prompts the user to enter a string, then creates a dictionary called `count` to keep track of how many times each character appears in the string. It loops through each character in the string, and if the character is already in the `count` dictionary, it increments the count by 1. If the character is not yet in the dictionary, it adds it with a count of 1. Finally, it prints out the character count for each character in the string.
