    Question 2
    CBSEENCO12011532

    Name the Python Library modules which need to be imported to invoke the following functions:
    (i) ceil()
    (ii) randint()

    CBSEENCO12011533

    Rewrite the following code in python after removing all syntax error(s). Underline each correction done in the code.

    TEXT=''GREAT
    DAY''
    for T in range[0,7]:
    print TEXT(T)
    print T+TEXT

    Solution
    TEXT = 'GREAT'
    DAY = ''
    for T in range (0,7):
    	print TEXT [T]
    	print T, TEXT

    The range(0,7) will give a runtime error as the index is out of range. It should be a range(0,6).

    Question 4
    CBSEENCO12011534

    Find and write the output of the following Python code:

    STR = ['90','10','30','40']
    COUNT = 3
    SUM = 0
    for I in [1,2,5,4]:
    	S = STR[COUNT]
    	SUM = float (S)+I
    	print SUM
    	COUNT-=1

    Solution

    The Output of the given Python code is,
    ['41', '32', '15', '94']
