Python String Formatting
String format()
The format() method allows you to format selected parts of a string.
Sometimes there are parts of a text that you do not control, maybe they come from a database, or user input?
To control such values,
add placeholders (curly brackets {}) in the text, and run the values through the
format() method:
price = 49
txt = "The price is {} dollars"
print(txt.format(price))
You can add parameters inside the curly brackets to specify how to convert the value:
Format the price to be displayed as a number with two decimals:
txt = "The price is {:.2f} dollars"
Multiple Values
If you want to use more values, just add more values to the format() method:
quantity = 3
itemno = 567
price = 49
myorder = "I want {} pieces of
item number {} for {:.2f} dollars."
print(myorder.format(quantity, itemno, price))
