1.
a=7
b=8

a+b=15>10 True
hello will be printed

in general, any two integers that their sum is > 10
will result in printing hello

2. 
Any non-zero value  = True
0 = False

a=123
b=2345
k = 123%10 + 2345%10=3+5=8
k%2=8%2=0
0 is False
python will be printed

In general, any two even numbers or any two odd numbers
will result in printing python

3.
a=2
b=0
a%3 = 2%3 = 2>=2 True hello

a+b=2
5//2=2
2!=2 False
python

a==(2%3)
2==2 True hello

4. 
python
python
hello

a=2 a==(2%3) must be True so a must be 2

NO VALUES a and b exist to print
python
python
hello

since if a is 2 
a%3>=2 is True and hello will be printed

5. 
a%b = 17 % 5 = 2
a%2 = 17%2 = 1

2 > 5 is False
1 is not zero so its True
False or True is True
hello will be printed 

6. 
d = not(c%2 and a>b)
c%2 = 6%2 = 0 False
a>b 17 > 5 True

False and True is False
not(False) is True

hello is printed

7. d = c%4 and a<b or not(a)

not(a)=not(17)=not(True)=False
c%4 = 6%4 = 2 - True
a<b  17 < 5 False

d = True and False or False = False
c%2 = 6%2 = 0 False

program is printed
