Why and how, second one is more powerful then 1st one

Question

print("your:" +a)
print("your:" .format(a=12)

Answer 1

There are several options recommended to make an ouput look formatted:

name = 'Paul'

print('Your name is ' + name)
print('Your name is', name)
print(f'Your name is {name}')

The first and the second are sufficient for simple output, the third is f-string and a real powerful version.

You'll have a better and self-explaining example, if you put three parameters of different data types at three different places within a message:

how_many = 5;
what = "apples";
cost = 4.99;

print("I want to buy " + str(how_many) + what + " for " + str(cost) + " dollars");

print(f"I want to buy {how_many} {what} for {cost} dollars");

print("I want to buy {how_many} {what} for {cost} dollars".format(how_many = 3, what = "bananas", cost = 2.99));
