Operators

+ - * / % ** // = += -= *= /= == != > < >= <= and or not

Example 1

a = 6
b = 2
a + b
returns: 8
a - b
returns = 4
a / b
returns: 3
a * b
returns: 12
a ** b
returns: 36

Example 2

a = 7
b = 3
a % b
returns: 1
a // b
returns: 2

Example 3

a =- 5
b = 2
a > b
returns: True
a < b
returns: False
a == b
returns: False
a >= 5
returns: True
b <= 1
returns: False

Example 4

a = 10
b = 2
a == 2 and b == 10
returns: False
a == 10 or b == 20
returns: True
not(a == 10)
returns: False
not(a == 2)
returns: True

Conditional Statements

Example 1

number = 5
if number == 10:
print("Number is 10")
elif number < 10:
print("Number is less than 10")
else:
print("Number is more than 10")

Returns: Number is less than 10

is_available = True
f is_available:
  print("Yes it is available")
else:
  print("Not available")

Example 3

is_available = True
if not is_available:
  print("Not available")
