Exercise-wise Answers & Revision Tips for Getting Started With Python Class 11

Exercise Solutions – NCERT Solutions Computer Science Chapter 5 Getting Started With Python (2025-26)

1. Which of the following identifier names are invalid and why?


  • i. Serial_no.
  • ii. 1st_Room
  • iii. Hundred$
  • iv. Total Marks
  • v. Total_Marks
  • vi. total-Marks
  • vii. _Percentage
  • viii. True

Answer:

  • Serial_no. – Invalid (contains a full stop “.”, which is not allowed in identifiers).
  • 1st_Room – Invalid (starts with a digit; identifiers cannot start with a number).
  • Hundred$ – Invalid (contains special symbol “$”, not permitted in identifiers).
  • Total Marks – Invalid (contains a space; spaces are not allowed in identifiers).
  • Total_Marks – Valid (follows all identifier naming rules).
  • total-Marks – Invalid (contains a hyphen “-”, which is not allowed).
  • _Percentage – Valid (can start with an underscore; allowed in identifiers).
  • True – Invalid (it is a Python keyword; cannot be used as an identifier).

2. Write the corresponding Python assignment statements:

  1. Assign 10 to variable length and 20 to variable breadth.
  2. Assign the average of values of variables length and breadth to a variable sum.
  3. Assign a list containing strings ‘Paper’, ‘Gel Pen’, and ‘Eraser’ to a variable stationery.
  4. Assign the strings ‘Mohandas’, ‘Karamchand’, and ‘Gandhi’ to variables first, middle and last.
  5. Assign the concatenated value of string variables first, middle, last to variable fullname (add spaces in between).

Answer:

  • length = 10
    breadth = 20
  • sum = (length + breadth)/2
  • stationery = ['Paper', 'Gel Pen', 'Eraser']
  • first = 'Mohandas'
    middle = 'Karamchand'
    last = 'Gandhi'
  • fullname = first + ' ' + middle + ' ' + last
