Question

ДАЮ 20 БАЛЛОВ!! Что будет выведено в результате работы следующей программы? a = 1; b = 2; c = 3 print("{:3}".format(a)) print("{:2}{:1}{}".format(b, b, b)) print("{}{}{}{}{}".format(c, c, c, c, c)) print("{:2}{:1}{}".format(b, b, b)) print("{:3}".format(a))

Answer 1

Можно было просто вставить этот код в интерпретатор Python)))

Answer 2

The program you provided will output the following:

  1
 222
33333
 222
  1

Let's break down the program step by step:

1. `a = 1; b = 2; c = 3`: This line assigns the values 1, 2, and 3 to variables `a`, `b`, and `c`, respectively.

2. `print("{:3}".format(a))`: This line uses string formatting to print the value of `a` with a width of 3 characters. Since `a` is 1, it will be printed as " 1" (two spaces followed by 1).

3. `print("{:2}{:1}{}".format(b, +b, +b))`: This line uses string formatting to print the values of `b` with different widths. The first `{}` will be replaced by `b` with a width of 2 characters, the second `{}` will be replaced by `+b` (which is equivalent to `2`) with a width of 1 character, and the third `{}` will be replaced by `+b` again. Since `b` is 2, the line will be printed as "22+2".

4. `print("{}{}{}{}{}".format(c, +c, +c, +c, +c))`: This line uses string formatting to print the values of `c` multiple times. Each `{}` will be replaced by `c` with a width of 1 character, and since `c` is 3, the line will be printed as "33333".

5. `print("{:2}{:1}{}".format(b, +b, +b))`: This line is similar to line 3 and will print "22+2".

6. `print("{:3}".format(a))`: This line is similar to line 2 and will print " 1".

Therefore, the final output will be:

  1
 222
33333
 222
  1

I hope this helps! Let me know if you have any further questions.
