Python Basic Operators
- 1. Title - Sub
- 2. Basic Operators • Python language supports the following types of operators. Arithmetic Operators Comparison (Relational) Operators Assignment Operators Logical Operators Bitwise Operators Membership Operators Identity Operators
- 3. Python – Arithmetic Operator a=10, b=20 Addition: a + b = 30 Subtraction: a - b = 20 Multiplication: a * b = 200 Division: a / b = 2 Modulus: a % b = 0 Increment: b++ = 21 Decrement: b-- = 19
- 4. Python – Comparison Operator a=10, b=20 Equal to: a == b : true Not equal to: a != b : false Greater than: a > b : false Less than: a < b : true Greater than or equal to: a >= b : false Less than or equal to: a <= b : true
- 5. Python – Assignment Operator Simple assignment operator: c=a+b //assign a+b to c Add AND assignment operator: c+=a //assign c=c+a Subtract AND assignment operator: c-=a //assign c=c-a Multiply AND assignment operator: c*=a //assign c=c*a Divide AND assignment operator: c/=a //assign c=c/a Modulus AND assignment operator: c*=a //assign c=c*a Lest shift AND assignment operator: c<<=2 //assign c=c<<2 Right shift AND assignment operator: c>>=2 //assign c=c>>2 Bitwise AND assignment operator: c&=2 //assign c=c&2 Bitwise exclusive AND assignment operator: c^=2 //assign c=c^2 Bitwise inclusive AND assignment operator: c|=2 //assign c=c|2
- 6. Python – Bitwise Operator //integer format a=60, b=13 //binary format a=0011 1100 b=0000 1101 a&b = 0000 1100 a|b = 0011 1101 a^b = 0011 0001 ~a = 1100 0011
- 7. Python – Logical Operator a=true b=false Logical AND: a AND b : true Logical OR: a OR b : true Logical NOT: NOT(a AND b) : false
- 8. Python – Membership Operator • in and not in are the membership operators; • It is used to test whether a value or variable is in a sequence. in True if value is found in the sequence not in True if value is not found in the sequence # Examples of Membership operator x = 'Geeks for Geeks' y = {3:'a',4:'b'} print('G' in x) print('geeks' not in x) print('Geeks' not in x) print(3 in y) print('b' in y) True True False True False
