PCEP 30-02 MOD 3
if-elif-else statement - correct answer ✔cascade- way of assembling the
statetment.


if the_weather_is_good:
go_for_a_walk()
elif tickets_are_available:
go_to_the_theater()
elif table_is_available:
go_for_lunch()
else:
play_chess_at_home()


range() function - correct answer ✔generates a sequence of numbers. It
accepts integers and returns range objects.


The syntax of range() looks as follows: range(start, stop, step),
where:
**start is an optional parameter specifying the starting number of the
sequence (0 by default)


**stop is an optional parameter specifying the end of the sequence generated
(it is not included),


**step is an optional parameter specifying the difference between the numbers
in the sequence (1 by default.)

, ex:
for i in range(3):


print(i, end=" ") # Outputs: 0 1 2




for i in range(6, 1, -2):


print(i, end=" ") # Outputs: 6, 4, 2


bitwise operators - correct answer ✔&, |, ^, ~, <<, >>


***allow you to manipulate single bits of data.


& (ampersand) - bitwise conjunction;
| (bar) - bitwise disjunction;
~ (tilde) - bitwise negation;
^ (caret) - bitwise exclusive or (xor).


& requires exactly two 1s to provide 1 as the result;


| requires at least one 1 to provide 1 as the result;


^ requires exactly one 1 to provide 1 as the result.
