Answer 2

Ofcourse.
format is a string method, which is used to insert values to string.
You can actually do the same thing with string concatenation, but using format method:
-You do not need to convert nonstring values to strings.
-Using format method can be more readable.

I will describe few main features of the format method, but it actually has much more features.

You can insert values in place of {}s in order you give arguments to the format method:
print("{} {} {}".format(1, True, "yesterday"))
#Output: 1 True yesterday

You can put numbers in {} to change the order of the passed values:
print("{2} {1} {0}".format(1, True, "yesterday"))
#Output: yesterday True 1

You can use keyword arguments to increase readability:
print("My name is {name}".format(name="... I don't know what my name is."))
#Output: My name is ... I don't know what my name is.

print("{x} + {y} = {z}".format(x=5, y=9, z="3?"))
#Output: 5 + 9 = 3?
