Simple example code round number if the second parameter is missing.

# even choice

Python round() Function

Round a number to the given number of decimal places

    print(round(2.665, 2))  
    # cannot be represented exactly as a float  
    print(round(2.675, 2))  



It’s important to be aware that round() uses the “round half to even” strategy, also known as “bankers’ rounding”, which means that when rounding to a specific number of digits, if the number is exactly halfway between two possible rounded values, it rounds to the nearest even number. For example:

print(round(2.5))  # Output: 2
print(round(3.5))  # Output: 4
