• The symbols used in computer programming are called syntaxes

• The rule following which different computer programs are written.

• All are correct

Answer explanation

The rules following which computer programs are written are call syntaxes.

Different programming languages (C, C++, Python etc.) follow different rules hence differ by their syntaxes

Python uses

• Blocks

• Braces

• Indentation

• Parentheses

Pyhton uses which of the following as translator?

• Interpreter

• Compiler

• Both

• Assembler

In which language is the Python programming created?

• C

When a string does not fit in single line, one can use the following quotes for multiple line string?

• Single Quotes

• Double Quotes

• Triple Quotes

• Quadruple

a=True; b=True; c=False

if a or b and c:

print('True')

else:

print('False')

• False

• True

• False or True

• No Output

Answer explanation

As per the precedence of operator the precedence of and is higher then or and therefore b and c will be evaluated first and gives False output and a is True and b and c is False so True or False will give True

The output -12%5 is

• -3

• -2

• 3

• 2

Answer explanation

R = N-Q*D

= -12-(-12//5*5)

=-12 + 15

= 3

a=500;b=300

print(a*bool(a//b) + b*bool(b//a))

will print?

• b

• a

• 500

• 300

Answer explanation

a*bool(a//b) + b*bool(b//a)

a=500 and b = 300

500*bool(500//300) + 300*bool(300//500)

500*bool(1) + 300 *bool(0)

500 + 0

So it print 500 as the greater value

2 ** 2** 3

• 256

Answer explanation

2 ** 2 ** 3

2** (2**3)

2**8

=256
