Analysis of the code execution:

  1. s = "информатика": The string "информатика" is assigned to the variable s.
  2. s1 = s [2:8]: This creates a slice of the string s starting from index 2 up to (but not including) index 8. The characters at these indices are 'ф', 'о', 'р', 'м', 'а', 'т'. So, s1 becomes "формат".
  3. s2 = s [1] + s [3:7]: This concatenates two slices. s [1] is the character at index 1, which is 'н'. s [3:7] includes characters from index 3 up to (but not including) index 7, which are 'р', 'м', 'а', 'т'. So, s2 becomes "н" + "рмат" = "нрмат".
  4. s3 = s [5] + s [0] + s [4]: This concatenates three parts. s [5] is the character at index 5, which is 'а'. s [0] is the character at index 0, which is 'и'. s [4] is the character at index 4, which is 'т'. So, s3 becomes "а" + "и" + "т" = "аит".
  5. print (s1): Prints the value of s1, which is "формат".
  6. print(s2): Prints the value of s2, which is "нрмат".
  7. print (s3): Prints the value of s3, which is "аит".

Output:

формат

нрмат

аит
