用 2 位小数格式化逗号 PYTHON

Question

I am trying to format a number to have commas and two decimal points at the end of it like: 100,000.00

This is what I have tried, but it won't work because I can't use these number formats on each other because they require a number to be inputted into the format.

"{:,}".format("{:.2f}".format(grossPay[i]))

So if you have any ideas on how I can do that, I would greatly appreciate it:D

Answer 1

Format specifiers can be combined:

>>> "{:,.2f}".format(100000)
'100,000.00'

Answer 2

if you just want to format any number into commas for 1000 and 2 decimals, all you need to do in Python is:

"{:,.2f}".format(grossPay[i])
