# Function to round a number to at most two decimal places
def round_to_two_decimals(number):
    rounded_number = round(number, 2)
    return rounded_number

# Example usage
example_number = 12.3456
rounded_example = round_to_two_decimals(example_number)

# Displaying results
print(f"Original number: {example_number}")
print(f"Rounded to two decimal places: {rounded_example}")

Explanation:

• We define a function round_to_two_decimals that takes a number as an argument and uses the round() function to round it to two decimal places.
• The round() function takes two arguments: the number to be rounded and the number of decimal places. In our case, we pass 2 as the second argument.
• We demonstrate the usage of the function with an example number (example_number), and then print both the original and rounded values.

Rounding numbers in Python is a straightforward task with the built-in round() function. By specifying the desired number of decimal places as the second argument, you can easily round numbers to meet your specific requirements. The provided code snippet serves as a simple yet effective demonstration of rounding to at most two decimal places in Python.
