The backslash () character is used to escape the meaning of characters that follow it by substituting their special meaning with an alternate interpretation. Escape sequences are also called as control sequences. For example,ĭifferent ways of string formatting in f-strings.Įscape Sequences are a combination of a backslash () followed by either a letter or a combination of letters and digits. This includes the decimal point and all the digits, i.e., before and after the decimal point. Precision refers to the total number of digits that will be displayed in a number.
By delinquency, strings are left-justified and numbers are right-justified. You can pad or create space around variable_name value element through width value. Also, using variable_name along with either width or precision values should be separated by a colon.
If they are specified, then both width and precision should be included within curly braces. Specifying width and precision values are optional. Within curly braces, you specify the variable_ name whose value will be displayed. The string_statement is a string consisting of a sequence of characters. The f character should be prefixed during f-string formatting. In Python source code, an f-string is a literal string, prefixed with ‘f’, which contains expressions within curly braces ‘’ It should be noted that an f-string is really an expression evaluated at run time and not a constant value. A python string format literal is what we see in the source code of a Python program, including the quotation marks. The f-strings provide a way to embed expressions inside strings literals, using a minimal syntax. A new python string format mechanism referred to as “f-strings” is becoming popular among Python community, taken from the leading character used to denote such python string format, and stands for “formatted strings”. Each of these methods has their advantages, but in inclusion, have disadvantages that make them cumbersome to use in practice. These include % -formatting and str.format(). Python String Format-Python supports multiple ways to format text strings.
