Positional Formatting

Instead of printing a message with some variables inserted, we can save string as the pattern with {}, and then insert variables when needed.

To execute this, we use the same approach as for f-strings. For example, we can save a pattern as a variable. Let it be the following:

python

Having such string saved, we can now use .format method to fill the {} places. If we leave these places empty, then the positional approach will be applied.

To fill the {} places we use .format() method with all the variables we want to insert from left to right. The number of {} blocks and variables/values within .format function should be the same. In our example, it should be as follows:

123
pattern = "The price of the {} is {} $" print(pattern.format("laptop", 1000)) print(pattern.format("sofa", 300))
copy

Create string named greeting in the format "Glad to see you, name on this wonderful day!". name and day are variables, already created for you. Then, print this string with the name and day inserted in the correct order.
