Lære Positional Formatting | Strings 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:

pattern = "The price of {} is {} $"

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))
