You can use the round function, which takes as its first argument the number and the second argument is the precision after the decimal point.
In your case, it would be:
answer = str(round(answer, 2))

Python round() Function
The round() function returns a floating point number that is a rounded version of the specified number, with the specified number of decimals. The default number of decimals is 0, meaning that the function will return the nearest integer.
How to round a whole number to 2 decimal places

Why does round(2.35, 1) return 2.4 (rounded up) but round(2.25, 1) returns 2.2 (rounded down)?
It’s a rounding method to balance error. If you always round up, it creates unbalanced weighting towards increasing. The idea is the digit in front of the 5 dictates the direction, odd rounds up while even rounds down. More on reddit.com
How to use the float() command to create 2 decimal places instead of one in a product of 2 numbers [the product is dollar amount]
You generally don't round until you go to display the value. You can use round for that, but since you just want to display it with two digits, you can use string formatting . In your case, something like print(f'{totalPay:.2f}'). .2f is the format specifier, saying round the float (f) to two decimal places (.2). More on reddit.com
Pythonic way to show 2 decimal places in f-strings?

Rounding to Two Decimal Places in Python | Codecademy
In accordance with standard rounding procedures in financial computations, ROUND_HALF_UP guarantees that numbers precisely halfway between two values round up to the larger value, while Decimal(‘0.01’) indicates that we wish to round to cents. In addition to the decimal module, for controlling numerical precision, Python offers string formatting. We will explore different string formatting methods, including f-strings, str.format(), and the % .2f approach, and discuss them in detail in the next section.

Use a format string. >>> a = 56 >>> "%.2f" % a '56.00' Or for python version >= 3.6: >>> a = 56 >>> f"{a:.2f}" '56.00'

The float printing routines use an accurate but much more computationally demanding algorithm to compute the number of digits after the decimal point. Alternatively, Python’s builtin round function uses a more accurate but slower algorithm for 64-bit floating point values: >>> round(56294995342131.5, 3) 56294995342131.5 >>> np.round(16.055, 2), round(16.055, 2) # equals 16.0549999999999997 (16.06, 16.05)

How to Round 2 Decimals with Python? - AskPython
May 12, 2023 - Now let us get on with another technique that can be used to round the decimal places to 2. The format( ) function makes use of the format specification operand ‘:’ to set the precision of the decimal places. Let us have a look at how it is done. ip = 2.1258908 op = format(ip,".2f") print("Rounded number:", op) Rounded number: 2.13 ... Rather than a function, this time it is a module which ought to be imported from the Python library using the following code.
