P#01.1 Fundas Opeartors

 # Python divides the operators in the following groups:
# Arithmetic operators   + -  * / % ** // 
# Assignment operators  =   +=  -= *= /= %= //= **=  &= |= ^= >>= <<= 
# Comparison operators == != > < >= <=
# Logical operators and or not 
# Identity operators is is not 
# Membership operators in not in 
# Bitwise operators & |  ^ ~ << >>

# Arithmetic operators   + -  * / % ** // 

x,y = 911,247

print('x=',x)

print('y=',y)

print()

print('x+y=',x+y)

print('x-y=',x-y)

print('x*y=',x*y)

print('x/y=',x/y)

print()

print('3**2=',3**2) #Exponentiation

print()

print('x%y=',x%y) #Modulus

print('x//y=',x//y)# FloorDivision

z = (y * ( x // y) + (x % y))

print(z)        # check Modulus + floor division

Output:
