Generate a string of the specified length with randomly chosen characters from the characters string. It will also ensure that the string contains at least one uppercase letter and one number from the required_characters string.

generate_string.py

import random

# Set the length of the string
length = 8

# Set the characters that the string can contain
characters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"

# Set the required characters
required_characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"

# Generate the string
string = ""
while len(string) < length:
    string += random.choice(characters)
    if any(char in string for char in required_characters):
        break

print(string)
