format string python using f

formatting strings is a common task in programming, and python provides a powerful and concise way to achieve this using f-strings. f-strings were introduced in python 3.6 and have quickly become a popular choice due to their simplicity and readability. in this tutorial, we'll explore the basics of format strings using f-strings in python, along with examples to illustrate various formatting options.
f-strings, or "formatted string literals," provide a concise and convenient way to embed expressions inside string literals, using curly braces {}. these expressions are evaluated at runtime and formatted using the surrounding string. f-strings are denoted by placing an 'f' or 'f' prefix before the string literal.
the basic syntax of an f-string is straightforward:
output:
in the example above, the value of the variable variable is inserted into the string at the specified location within the curly braces.
f-strings allow you to include any valid python expression inside the curly braces. for example:
output:
you can format numeric values within f-strings to control precision, width, and other aspects. for example:
output:
in this example, :.2f specifies that the floating-point number should be formatted with two decimal places.
f-strings also support formatting date and time objects using the datetime module. here's an example:
output:
in this case, the :%y-%m-%d %h:%m:%s specifies the desired format for the date and time.
you can control the width, alignment, and padding of values within the formatted string. for instance:
output:
here, :5 specifies that the width of the field should be 5 characters, and the number is right-aligned within that space.
f-strings provide a concise and powerful way to format strings in python, offering a wide range of options for expressing and formatting values. whether you're working with simple variables, complex expressions, or date and ...
