**********************************************************************************************************************************************************
1. What are the two values of the Boolean data type? How do you write them?

Ans: True and False
Boolean = True
Boolean = False
**********************************************************************************************************************************************************

2. What are the three Boolean operators?

Ans: 'And', 'Or' and 'Not'
**********************************************************************************************************************************************************

3. Write out the truth tables of each Boolean operator (that is, every possible combination of Boolean values for the operator and what they evaluate to).

Ans:
3 > 2 & 3 > 1 = TRUE
(2>1) & (3>2) = TRUE
2 > 1 & 3 > 2 = FALSE
2 > 1 & 2 > 3 = FALSE
(2>1) | (3>2) = TRUE
2 > 1 | 3 > 2 = FALSE
2 > 1 | 2 > 3 = FALSE
(2>1) | (2>3) = TRUE
2 > 1 != 3 > 2 = TRUE
2 > 1 != 2 > 3 = FALSE
**********************************************************************************************************************************************************
4. What do the following expressions evaluate to?
(5 > 4) and (3 == 5)
not (5 > 4)
(5 > 4) or (3 == 5)
not ((5 > 4) or (3 == 5))
(True and True) and (True == False)
(not False) or (not True)

Ans:
* (5 > 4) and (3 == 5) - FALSE
* not (5 > 4) - FALSE
* (5 > 4) or (3 == 5) - TRUE
* not ((5 > 4) or (3 == 5)) - FALSE
* (True and True) and (True == False) - FALSE
* (not False) or (not True) - TRUE
**********************************************************************************************************************************************************
5. What are the six comparison operators?

Ans:
* "==" - if the values of two operands are equal then it is 'TRUE' else 'FALSE'
* "!=" - if the values of two operands are not equal then it is 'TRUE' else 'FALSE'
* ">" - if the value of left operand is greater than the value of right operand, the condition becomes 'TRUE' else 'FALSE'
* "<" - if the value of left operand is lesser than the value of right operand, the condition becomes 'TRUE' else 'FALSE'
* ">=" - if the value of left operand is greater than or equal to the value of right operand, the condition becomes 'TRUE' else 'FALSE'
* "<=" - if the value of left operand is lesser than ore equal to the value of right operand, the condition becomes 'TRUE' else 'FALSE'
**********************************************************************************************************************************************************
6. What is the difference between the equal to operator and the assignment operator?

Ans:
Equal to operator is '==' and assignment operator is "="
When we use assignment operator "=", it means it assigns a value provided in right side to left side variable. Like 'a = 5', which means it assigns 5 to variable 'a'
Equal to operator "==" is used to compare the two values. Like '5' == '5' if it is correct then returns 'TRUE' else 'FALSE'
**********************************************************************************************************************************************************
7. Identify the three blocks in this code:
spam = 0
if spam == 10:
 print('eggs')
 if spam > 5:
 print('bacon')
 else:
 print('ham')
 print('spam')

 Ans:
* First we initiated a variable 'spam' with a value as '0'
* Then we are checking the condition if it is '10', it is not because it is '0', hence it will not 'print('eggs')'
* Again we are checkint the condition if it is '5', it is not because it is '0', hence it will not 'print('bacon')'
* then it goes to 'else:' part and prints ('ham' and 'spam')
**********************************************************************************************************************************************************
8. Write code that prints Hello if 1 is stored in spam, prints Howdy if 2 is stored in spam, and prints Greetings! if anything else is stored in spam

Ans:
user_value = int(input('Provide a number to get the result: '))
if user_value == 1:
print ('Hello')
elif user_value == 2:
print ('Howdy')
else
print ('Greetings!')
**********************************************************************************************************************************************************
9. What can you press if your program is stuck in an infinite loop?

Ans: CTRL + C
**********************************************************************************************************************************************************

10. What is the difference between range(10), range(0, 10), and range(0, 10, 1) in a for loop?

Ans:
range(10)
for i in range(10):
	print(i)

which prints from 0 to 9

range(0,10)
for i in range(0,10):
	print(i)

similar, which also prints from 0 to 9

range(0,10,1)
for i in range(0,10,1):
	print(i)

similar, which also prints from 0 to 9
