How to apply "%.02f" in Python format function?

I'm new to python, recently I have migrated to Python 3 and I'm trying to get used to the format() function.

What I'm trying to do is to print() the temperature I create in floating-points, like so:

temperature = [23, 24, 25, 26, 27]
print("Today's temperature is %.02f" % (temperature[0]))

Instead of using %.02f, I would like to know how that could be written in the format() function instead of the % percentage.

As of Python 3.6, you can use f-strings for such formatting:

>>> temperature = [23, 24, 25, 26, 27]
>>> print(f'Temperature is: {temperature[0]:.2f}')
Temperature is: 23.00

You will have to use {:.02f}

>>> temperature = [23, 24, 25, 26, 27]
>>> print("Today's temperature is %.02f" % (temperature[0]))
Today's temperature is 23.00
>>> print("Today's temperature is {:.02f}".format(temperature[0]))
Today's temperature is 23.00

More information can be found in the documentation. However do see Format Examples

'%03.2f' can be translated to '{:03.2f}'
