a=a*2
b=b+5
print(a,b)

Answer 1

$\texttt{\textsf{\large{\underline{Given C{o}de}:}}}$

a, b = 10, 12

a = a * 2

b = b + 5

print(a, b)

$\texttt{\textsf{\large{\underline{O{u}tput}:}}}$

The output for the program is:

20 17

$\texttt{\textsf{\large{\underline{Explanation}:}}}$

• Here, two variable named a and b are declared.
• Variable a stores value 10 and the other stores value - 12.
• In the second line, the value of variable a is double. '*' operator is used to perform multiplication. a * 2 = 20 and now a = a * 2 or a = 20.
• In the third line, 5 is added to the variable b. '+' operator is used for addition and for concatenating two or more strings. b = b + 5 or b = 12 + 5 or b = 17. So, b becomes 17.
• In the fourth line, the values of a and b are displayed on the screen.
