•  Analysing the problem.
                  •  Developing the solution.
                  •  Coding and implementation.

               5.  How did Python get its name?
              Ans.  Guido van Rossum designed Python and released in 1991. He wanted to give a unique name to it. So, he named it after
                  the famous BBC comedy TV show "Monty Python's Flying Circus".

               6.  Why is Python considered as a high-level language?
              Ans.  Python simplifies the process of developing a program. The code is more close to human language and away from
                  machine language.

               7.  Name different modes of working in Python.
              Ans.  The two different modes of working in Python are:
                  •  Interactive Mode
                  •  Script Mode

               8.  What are tokens in Python? Name a few of them.
              Ans.  Tokens are the smallest meaningful unit of a program. Tokens supported by Python are Keywords, Identifiers, Literals,
                  Operators and Punctuators.
               9.  What is the use of if statement in Python?

              Ans.  It executes the set of statements based on a condition.

               10.  How is a block of statements identified in Selection or Iteration?
              Ans.  A block is identified by using an indentation (minimum 1 space). Ensure that all statements in one block are indented
                  at the same level.
               11.  What is iteration?

              Ans.  Sometimes we have a situation where we need to repeat a set of instructions a number of times then we put it in a loop
                  which repeats automatically. This is called Iteration.
               12   What is the use of the + operator with lists?

              Ans.  The + operator is used to concatenate the list with another list.
               13.  What do you mean by traversing a list?
              Ans.  Traversing a list means to visit each element and process it as required by a program.

               14.  What is the use of the pop( ) function?

              Ans.  The pop( ) function removes an element from the list based on the index number specified in the function and returns
                  the deleted value.

            B.  Long answer type questions:
               1.  What is sequential flow? Explain with an example.

              Ans.  In  sequential  flow,  the  statements  are  placed  one  after  the  other  and  the  flow  of  execution  occurs  starting  from
                  line1, line2 and so on with a top to down approach. It is the default type followed in any programming language. For
                  example, Steps for calculating percentage of any student
                  Input marks of English, Hindi and Math
                  Total the marks

                                                                                   Introduction to Python  335
