The above number can be specified with a zero on the left side (e.g.

In case of %5d, “123” will be substituted as ” 123″, 12 is substituted as ” 12″, etc. %5d), and Python will give the integer left padding so that the total number of character the integer takes is equal to the number specified.

We can specify a number between % and the format specifier (e.g.

To see the full list of specifiers, we can see the Python docs.

In the example, d is the format specified for integers, s for strings, f for float or decimal, etc. Notice that inside the string we have written %d, whatever comes after % is called the format specifier. In the above example, we have two integers to be substituted, so we write the two integers in a tuple and put it as the second operand. This will tell Python that an integer is to be substituted here.Īfter the string, we use the % operator and write the second operand which is a tuple containing the list of integers to be substituted in the correct order. In the double quotes, we are writing the entire string that is to be printed, but instead of the integers, we are writing %d. This works very similarly to the printf statement in C. This is an old way for string formatting is still useful for simple operations. Today we will be discussing three ways of formatting strings: Note: If we do print('The square of', input, 'is', result), this will print four different things, it will not generate a formatted string, so this doesn’t count as string formatting. We cannot write a complete string like this because we have two integers to insert in the string, so we will need a way to generate this string. In your input, you get an integer from the user, and in the output, you tell the user that the square of the integer is so and so.įor Example, if the input is 12, then you’ll need to print “The square of 12 is 144”. Let us say you are writing a program that prints the square of a number.

In this tutorial, we will discuss the different ways and how to use them. String formatting, as the name suggests, refers to the multiple ways to format strings in Python.
