Formatting Number With Comma

I am trying to put comma's on a number without striping any numbers after the decimal point.

number

12018093.1000

results

12,018,093.10

I tried this code but it strips away the last 0 which I don't know why.

rps_amount_f = ("{:,}".format(float(rps_amount_f)))

You said that you only want one zero so really isn't the solution just to add a 0 to the end of the string? Anyway here's my solution:

if("." in str(rps_amount_f)):
    rps_amount_f = ("{:,}".format(float(rps_amount_f)) + "0")
else:
    rps_amount_f = ("{:,}".format(float(rps_amount_f)))

If you want two decimal places you just get rid of the if statement and round it.

print("{:,.4f}".format(float(rps_amount_f))) # 12,018,093.1000

I'm not sure why the zeros are stripped away in your example, although this may be a solution using an f-string:

rps_amount_f = 12018093.1

rps_amount_f_str = f"{rps_amount_f:,.10f}"

Here '10' before the f is the decimal precision you want to have in the string, i.e. 10 decimals in this case.
