Introduction to PythonOperators
Operators are special symbols or
keywords used to perform operations on
variables and values.
They are fundamental to building
expressions and controlling program
flow.
Python provides a rich set of operators to
perform various arithmetic, comparison,
and logical operations.
3.
Arithmetic Operators
Arithmetic operatorsare used to
perform basic mathematical operations
such as addition, subtraction,
multiplication, and division.
Examples include +, -,
, /, %, //, and .
4.
Assignment Operators
Assignment operatorsare used to assign
values to variables.
The basic assignment operator is '=', but
compound operators like '+=', '-=', '
=' are also common.
5.
Comparison (Relational) Operators
Comparisonoperators compare two
values and return a boolean result (True
or False).
Examples include ==, !=, >, <, >=, and <=.
They are often used in conditional
statements and loops to control the flow
of a program.
6.
Logical Operators
Logical operatorsare used to combine
multiple boolean expressions.
Python includes 'and', 'or', and 'not' as
logical operators.
These operators help evaluate complex
conditions and make decisions in code.
7.
Bitwise Operators
Bitwise operatorsperform operations on
the binary representations of integers.
Examples include &, |, ^, ~, <<, and >>.
They are useful in low-level
programming, encryption, and
performance optimization tasks.
8.
Membership and IdentityOperators
Membership operators 'in' and 'not in'
test whether a value exists within a
sequence or collection.
Identity operators 'is' and 'is not' check
whether two references point to the
same object.
These operators are essential for object
comparison and collection membership
testing.
9.
Operator Precedence andAssociativity
Operator precedence determines the
order in which operators are evaluated in
an expression.
Associativity defines the order of
evaluation for operators with the same
precedence.
Proper understanding of precedence and
associativity is crucial for writing correct
and efficient code.
