Python f string format float | Example code

In Python programming, formatted string literals, are simply called “f-strings“. They are called f-strings because you need to prefix a string with the letter ‘F in order to get an f-string. The letter ‘f’ also indicates that these strings are used for formatting

f'{value:{width}.{precision}}'

Include the type specifier in your format expression:

>>> a = 10.1234
>>> f'{a:.2f}'
'10.12'

where:

• value is any expression that evaluates to a number
• width specifies the number of characters used in total to display, but if value needs more space than the width specified then the additional space is used.
• precision indicates the number of characters used after the decimal point
