| Note: Q1 is compulsory. Attempt one question each from the Units I, II, III & IV | |
| Q1 Discuss : (2.5*8=20) | |
| (a) Write a Python program to print the prime numbers of up to a given number, accept the number from the user. | |
| (b) Write a Python program to accepts a string and calculates the number of digits and letters. | |
| (c) Write a program to check if the word ‘open’ is present in the “This is open source software”. | |
| (d) Write a Python Program that reads n numbers separated by a space in one line and displays distinct numbers. For example Input : 1 1 1 1 1 2 2 2 2 Output : 1 2 | |
| (e) Write a Python function to calculate the factorial of a number (a non-negative number). The function accepts the number as an argument. | |
| (f) Write a Python Program to handle that exception that occurs when accessing an index out of range in a list. | |
| (g) Given a numpy array, write a function to sort it in descending order. | |
| (h) Use regular expression to check if the string ends with “World!”. If a match is found , it prints “Match Found!” otherwise, it prints “Match not found”. | |
