PRECEDENCE IN PYTHON

 PRECEDENCE IN PYTHON 

In Python, the precedence of operators follows a specific hierarchy. Here is the precedence of operators in Python, from highest to lowest:

  1. Parentheses:

  2. Operators enclosed in parentheses are evaluated first. Parentheses can also be used to override the default precedence and enforce a specific order of evaluation.


  4. Exponentiation:

  5. The exponentiation operator (**) is evaluated next. For example, in the expression 2 ** 3, the exponentiation operator has higher precedence than any other operator, so the result would be 8.


  7. Unary Operators:

  8. Unary operators, such as negation (-) or logical negation (not), are evaluated next. These operators operate on a single operand. For example, in the expression -3 * 4, the unary negation operator has higher precedence than the multiplication operator, so the result would be -12.


  10. Multiplication, Division, Floor Division, and Modulo: Multiplication (*), division (/), floor division (//), and modulo (%)

  11. operators are evaluated from left to right. For example, in the expression 4 * 3 / 2, the multiplication and division operators have the same precedence, so they are evaluated from left to right, resulting in 6.0.


  13. Addition and Subtraction: Addition (+) and subtraction (-)

  14. operators are evaluated from left to right. For example, in the expression 6 - 2 + 4, the subtraction and addition operators have the same precedence, so they are evaluated from left to right, resulting in 8.


  16. Comparison Operators:

  17. Comparison operators, such as less than (<), greater than (>), less than or equal to (<=), greater than or equal to (>=), equality (==), and inequality (!=), are evaluated next. They compare two operands and return a Boolean value (True or False) based on the comparison result.


  19. Logical Operators:

  20. Logical operators, such as logical NOT (not), logical AND (and), and logical OR (or), are evaluated next. They operate on Boolean values and return a Boolean result.

  21. Bitwise Operators: Bitwise operators, such as bitwise NOT (~), bitwise AND (&), bitwise OR (|), bitwise XOR (^), left shift (<<), and right shift (>>), are evaluated next. They operate on integer values at the binary level.


  23. Membership Operator:

  24. Membershiptors: operators, such as in and not in, are evaluated next. They test for membership in a sequence or collection.

  25. Identity Operators: Identity operators, such as is and is not, are evaluated next. They test for object identity.


  27. Assignment Operators:

  28. Assignment operators, such as assignment (=), compound assignment (+=, -=, *=, /=, //=, %=, **=, &=, |=, ^=, >>=, <<=), and others, are evaluated last. They assign a value to a variable or modify its value.

  30. Remember that when an expression contains multiple operators of the same precedence, they are evaluated from left to right. Also, as mentioned earlier, using parentheses can override the default precedence and enforce a specific order of evaluation.

COMPARISION EXPRESSION

COMPARISION EXPRESSION    In Python, comparison expressions are used to compare values and return a Boolean result (True or False) based on the comparison. Here are the commonly used comparison operators in Python: Equal to (==): Checks if two values are equal. Example: 5 == 5 evaluates to True . Not equal to (!=) : Checks if two values are not equal. Example: 5 != 3 evaluates to True. Greater than (>) : Checks if the left operand is greater than the right operand. Example: 5 > 3 evaluates to True. Less than (<): Checks if the left operand is less than the right operand. Example: 3 < 5 evaluates to True. Greater than or equal to (>=) : Checks if the left operand is greater than or equal to the right operand. Example: 5 >= 5 evaluates to True. Less than or equal to (<=) : Checks if the left operand is less than or equal to the right operand. Example: 3 <= 5 evaluates to True. These comparison operators can be used with various data types,...

LOGICAL EXPRESSION

LOGICAL EXPRESSION    In Python, logical expressions are used to evaluate the truthiness or falsiness of a combination of conditions. Logical expressions involve the use of logical operators, such as "and", "or", and "not". These operators allow you to combine multiple conditions and evaluate them as a single Boolean result. Here are the logical operators in Python: Logical AND (and): Returns True if both conditions on the left and right are True. Example: x > 5 and y < 10 evaluates to True if x is greater than 5 and y is less than 10. Logical OR (or) : Returns True if at least one of the conditions on the left or right is True. Example: x > 5 or y < 10 evaluates to True if either x is greater than 5 or y is less than 10. Logical NOT (not): Reverses the truthiness of a single condition. If the condition is True, it returns False, and vice versa. Example: not x > 5 evaluates to True if x is not greater than 5. Here's an example ...
