F-strings can also be used to display percentages. By using the percent format specifier (%), you can easily convert a decimal value to a percentage, and you can control the number of decimal places shown. main.py #!/usr/bin/python val = 1/7.0 print(f'{val}') print(f'{val:.2%}...

It determines the type of conversion that Python applies to the corresponding value before inserting it into the format string. Here’s a table that lists the possible conversion types: <type>Conversion Type d, i, u Decimal integer x, X Hexadecimal integer o Octal integer f, F Floating-point...
In this example, note that each replacement field contains a string that starts with a colon. That’s a format specifier. The .2f part tells Python that you want to format the value as a floating-point number (f) with two decimal places (.2). Note: To learn more about the formatting...
If the precision field is missing, the directive can take the form %min(type), so, for example, %5d ensures that a decimal number has at least 5 fields and %20f ensures that a floating-point number has at least 20. Let's look at the use of these directives in an interactive ...
However, in the case of floating-point numbers, the %d operator automatically converts them to decimal values. An example code is given below. area = 24.6 print("The area of this plot is %d sq meter." % area) Output: The area of this plot is 24 sq meter. %s in Python String ...
Python Type conversion is done before formatting the string.!sapplies thestr(value)method to a value, while!rapplies therepr(value)method. For example, if we wanted to format a string in quotes, we would use the!rmodifier. In the code below, we have defined the__str__()method. This...
You can also format a value directly without keeping it in a variable: Example Display the value95with 2 decimals: txt = f"The price is {95:.2f} dollars" print(txt) Try it Yourself » Perform Operations in F-Strings You can perform Python operations inside the placeholders. ...
