When it comes to float numbers, you can use format specifiers:
f'{value:<width>.<precision>}'
where:
valueis any expression that evaluates to a numberwidthspecifies the number of characters used in total to display, but ifvalueneeds more space than the width specifies then the additional space is used.precisionindicates the number of characters used after the decimal point
What you are missing is the type specifier for your decimal value. In this link, you an find the available presentation types for floating point and decimal.
Here you have some examples, using the f (Fixed point) presentation type:
# notice that it adds spaces to reach the number of characters specified by width
In [1]: f'{1 + 3 * 1.5:10.3f}'
Out[1]: ' 5.500'
# notice that it uses more characters than the ones specified in width
In [2]: f'{3000 + 3 ** (1 / 2):2.1f}'
Out[2]: '3001.7'
In [3]: f'{1.2345 + 4 ** (1 / 2):9.6f}'
Out[3]: ' 3.234500'
# omitting width but providing precision will use the required characters to display the number with the the specified decimal places
In [4]: f'{1.2345 + 3 * 2:.3f}'
Out[4]: '7.234'
# not specifying the format will display the number with as many digits as Python calculates
In [5]: f'{1.2345 + 3 * 0.5}'
Out[5]: '2.7344999999999997'

How to Format Floats Within F-Strings in Python – Real Python
April 24, 2024 - To format a float for neat display within a Python f-string, you can use a format specifier. In its most basic form, this allows you to define the precision, or number of decimal places, the float will be displayed with.
Using an f-string with multiple parameters (decimal places plus string padding)
f"{x:<5.0f}" should do it. You can't directly chain the colons like you tried. You can actually put entire fstrings inside of other fstrings, but I wouldn't recommend it. More on reddit.com

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

r/learnpython on Reddit: Pythonic way to show 2 decimal places in f-strings?
March 1, 2019 -
I've got a number that needs to be rounded to 2 decimal places. Getting the round is easy, but if the number is a whole number or only has 1 digit beyond the decimal the rounding doesn't properly show 2 decimal places.
answer = 1 print(round(float(answer),2)) >> 1.0
I really like f-strings, so I would use this:
answer = 1
print(f"{round(float(answer),2):.2f}")
>> 1.00
Is there a neater or more readable method of doing this?

Also, formatting to round things is one instance where I sometimes prefer the .format() method to fstrings, as you can define the formatting once and use it again and again:
>>> FORMAT_2DP = "{:.2f}"
>>> numbers = 1, 3, 4, 5
>>> for number in numbers:
... print(FORMAT_2DP.format(number))

Looking for some assistance here.
I can clearly do this with multiple steps, but I'm wondering the optimal way.
if I have a float 12.34, I want it to print was "12___" (where the underscores just exist to highlight the spaces. Specifically, I want the decimals remove and the value printed padded to the right 5 characters.
The following does NOT work, but it shows what I'm thinking
print(f'{myFloat:.0f:<5}')
Is there an optimal way to achieve this? Thanks

Hmm… print(f”{my_float : ‘_’<5,.0f}) Seems about right for this You basically just have to put the padding before the float stuff, just one of Python’s syntax things. (I think) You also have two ‘ : ‘ in there and that just looks wrong anyway. So remove that. I added the underscore because I wasn’t 100% you wanted it or not, and also to ask…where else would you have put that ‘_’ in my code and have it make sense., which I think is illuminating. As padding is much more an important operation here than rounding.

You should use the new format specifications to define how your value should be represented:
>>> from math import pi # pi ~ 3.141592653589793
>>> '{0:.2f}'.format(pi)
'3.14'
The documentation can be a bit obtuse at times, so I recommend the following, easier readable references:
- the Python String Format Cookbook: shows examples of the new-style
.format()string formatting - pyformat.info: compares the old-style
%string formatting with the new-style.format()string formatting
Python 3.6 introduced literal string interpolation (also known as f-strings) so now you can write the above even more succinct as:
>>> f'{pi:.2f}'
'3.14'

The String Formatting Operations section of the Python documentation contains the answer you're looking for. In short:
"%0.2f" % (num,)
Some examples:
>>> "%0.2f" % 10
'10.00'
>>> "%0.2f" % 1000
'1000.00'
>>> "%0.2f" % 10.1
'10.10'
>>> "%0.2f" % 10.120
'10.12'
>>> "%0.2f" % 10.126
