To determine if a given integer is between two different numbers (e.g., greater than or equal to 10000 and less than 30000), you need to adjust your conditional statement. Currently, you are using number >= 30000, which would include numbers greater than or equal to 30000. Instead, you should use number < 30000 to exclude 30000. Here's the corrected code:

if 10000 <= number < 30000:

print("You have to pay 5% taxes")

In the updated code, the and operator is used to check two conditions: number >= 10000 ensures that the number is greater than or equal to 10000, and number < 30000 ensures that the number is less than 30000. If both conditions are satisfied, the message "You have to pay 5% taxes" will be printed.
