Python f string format float | Example code

  • by

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


Include the type specifier in your format expression:

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


  • 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
