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
'10.13'

Add a decimal point with number of digits .2f see the docs: https://docs.python.org/2/library/string.html#format-specification-mini-language :
In [212]:
"{0:,.2f}".format(2083525.34561)
Out[212]:
'2,083,525.35'
For python 3 you can use f-strings (thanks to @Alex F):
In [2]:
value = 2083525.34561
f"{value:,.2f}"
Out[2]:
'2,083,525.35'

Example:
hourlyRate = 20 hoursLabor = 1.6
I want the answer to show “32.00” instead of “32” or “32.0”.
What I have so far produces the number 32.0:
totalPay = float(hourlyRate * hoursLabor)
print(totalPay)
I’m obviously very new at this. Just getting some beginner’s practice :)

Binary and decimal aren't perfectly compatible, so it's true that round() won't always work. If precision is only needed for two decimal places, you could multiply the number by 100, round, cast to int, and divide by 100 again. (In that case, round() should work as expected because 0.5 can be represented as finite binary, which means everything >= .5 will be rounded up, everything < .5 rounded down)
