printf 2 decimal places python

How can I format a decimal to always show 2 decimal places?

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'

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 :)

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).

This should do it print(f'{totalPay:.2f}')
