What is %s %d %f in python?
This is the Exercise: Show As it says, %s (of string) is to replace a string, %f (of float) is to replace a float, and %d (of integer) is to replace an integer

Just to add to @A. Gutierrez's answer and provide explanation as to why we do this; In the prior examples (on the site mentioned) we are told that Python "doesn't support mixing operators between numbers and strings." This solution allows you to overcome this. For example, you would have noticed that:
prints
But using the "+ variable" syntax:
Would have thrown the following error:

1 In this article, we will see the difference between %s and %d in Python. Here, we start with the proper explanation of one at a time, then both, and at last compare these. What does %s do in Python?The % symbol is used in Python with a large variety of data types and configurations. It is used as an argument specifier and string formatter. %s specifically is used to perform the concatenation of strings together. It allows us to format a value inside a string. It is used to incorporate another string within a string. It automatically provides type conversion from value to string. How to Use %s in PythonThe %s operator is put where the string is to be specified. The number of values you want to append to a string should be equivalent to the number specified in parentheses after the % operator at the end of the string value. The following code illustrates the usage of the %s symbol : Python3
Output Hey, Geek! What does %d do in Python?The %d operator is used as a placeholder to specify integer values, decimals, or numbers. It allows us to print numbers within strings or other values. The %d operator is put where the integer is to be specified. Floating-point numbers are converted automatically to decimal values. Python3
Output 2021 is here!! How to Use %d in PythonThe decimal and rational numbers are rounded off to the absolute integral part and the numbers after the decimal are scraped off, that is only the integers are extracted. The following code illustrates the usage of %d with decimal and fractional numbers: Python3
Output Rational number formatting using %d 2 is equal to 8/3 using this operator. Decimal number formatting using %d 10 is equal to 10.9785 using this operator. Difference Between %s and %d?We can use a combination of operators also within a single program. Before that first, clear some concepts by comparing as given below :
Common Errors Using %s and %dExample 1:The %s automatically converts a numeric value to a string without throwing an error. Python3
Output Using %s Sita's age is 22. Example 2:The %d, however, can only be used for numeric values. Otherwise, an error is returned. Python3
Error Using %d Traceback (most recent call last): File " What does %s mean in python?%s specifically is used to perform concatenation of strings together. It allows us to format a value inside a string. It is used to incorporate another string within a string. It automatically provides type conversion from value to string.
What is %d of %D in python?What does %d do in Python? The %d operator is used as a placeholder to specify integer values, decimals, or numbers. It allows us to print numbers within strings or other values. The %d operator is put where the integer is to be specified.
How do you use %s %d in python?In, Python %s and %d are used for formatting strings. %s acts a placeholder for a string while %d acts as a placeholder for a number. Their associated values are passed in via a tuple using the % operator. This code will print abc 2.
What is %s in python print?%s acts as a placeholder for the real value. You place the real value after the % operator. This method is often referred to as the "older" way because Python 3 introduced str. format() and formatted string literals (f-strings).
