Find Pass/ Fail.
mark = int(input())
if mark>=33:
print("Pass")
else:
print("Fail")

Find Voter or Not Voter.
age = int(input())
if age>=18:
print("Voter")
else:
print("Not Voter")

Is a number Positive/ Negative/ Zero?
num = int(input())
if num>0:
print("Positive")
elif num<0:
print("Negative")
else:
print("Zero")

Find Grade of Exam.
mark = int(input())
if mark>=80:
print("A+")
elif mark>=70:
print("A")
elif mark>=60:
print("B")
elif mark>=50:
print("C")
elif mark>=40:
print(“D")
elif mark>=33:
print("E")
else:
print("F")

Find Maximum between 2 number.
a = int(input())
b = int(input())
if a>b:
print(a)
else:
print(b)

Find Maximum between 2 number. [2 (no way)]
a = int(input())
b = int(input())
max = max(a, b)
print("{} is maximum".format(max))

Find Minimum between 2 number.
a = int(input())
b = int(input())
if a<b:
print(a)
else:
print(b)

Find Maximum between 3 number.
a = int(input())
b = int(input())
c = int(input())
if a>b and a>c:
print(a)
elif b>a and b>c:
print(b)
else:
print(c)

Find Minimum between 3 number.
a = int(input())
b = int(input())
c = int(input())
if a<b and a<c:
print(a)
elif b<a and b<c:
print(b)
else:
print(c)

Check is a number EVEN or ODD.
num = int(input())
if num%2==0:
print("Even")
else:
print("Odd")

Check is a year Leap Year or Not.
year = int(input())
if year%400==0:
print("Leap Year")
elif year%100==0:
print("Not Leap Year")
elif year%4==0:
print("Leap Year")
else:

Check is a year Leap Year or Not. [2]
year = int(input())
if year%4==0 and not(year%100==0) or year%400==0:
print("Leap Year")
else:

Comparisons (Relational Operator)
• < (less than)
• <= (less than or equal)
• > (greater than)
• >= (greater than or equal)
• == (equal)
• != (not equal)
• is (object identity)
• is not (negated object identity)

Logical Operator
• and
• or
• not

Bitwise Operator
• (|) bitwise or
• (^) bitwise exclusive or (xor)
• (&) bitwise and
• (<<) left shift
• (>>) right shift
• (~) complement
