Python - Format - Strings
String Format
As we learned in the Python Variables chapter, we cannot combine strings and numbers like this:
But we can combine strings and numbers by using the format() method!
The format() method takes the passed arguments,
formats them, and places them in the string where the placeholders
{} are:
Example
Use the format() method to insert numbers
into strings:
age = 36
txt = "My name is John, and I am {}"
print(txt.format(age))

The format() method takes unlimited number of arguments, and are placed into the respective placeholders:
Example
quantity = 3
itemno = 567
price = 49.95
myorder = "I want {}
pieces of item {} for {} dollars."
print(myorder.format(quantity,
itemno, price))

You can use index numbers {0} to be sure the arguments are placed
in the correct placeholders:
Example
quantity = 3
itemno = 567
price = 49.95
myorder = "I want to pay {2}
dollars for {0} pieces of item {1}."
print(myorder.format(quantity,
itemno, price))
