I have a function taking float arguments (generally integers or decimals with one significant digit), and I need to output the values in a string with two decimal places (5 -> 5.00, 5.5 -> 5.50, etc). How can I do this in Python?


You could use the string formatting operator for that:

>>> '%.2f' % 1.234
'1.23'
>>> '%.2f' % 5.0
'5.00'

The result of the operator is a string, so you can store it in a variable, print etc.

f-string formatting:

This is new in Python 3.6 - the string is placed in quotation marks as usual, prepended with f'... in the same way you would r'... for a raw string. Then you place whatever you want to put within your string, variables, numbers, inside braces f'some string text with a {variable} or {number} within that text' - and Python evaluates as with previous string formatting methods, except that this method is much more readable.

>>>a = 3.141592
>>>print(f'My number is {a:.2f} - look at the nice rounding!')

My number is 3.14 - look at the nice rounding!

You can see in this example we format with decimal places in similar fashion to previous string formatting methods.

NB a can be an number, variable, or even an expression eg f'{3*my_func(3.14):02f}'.

Going forward, with new code f-strings should be preferred over common %s or str.format() methods as f-strings are much faster.

How to truncate a float in Python, In python, you have floats and decimals that can be rounded. First we take a float and convert it to a decimal x = Decimal(16.0/7) # Then we round it to 2 places  The two decimal places are the two digits after the decimal point in a float variable. You can also round float to 3 decimal places after the decimal point. The round () is the commonly known function of Python to perform this task. However, you will learn some other methods with other functions of Python.
