Study Notes

Input Function

The input() function takes user input as a string.
The input is always a string, even if the user enters a number.

Arithmetic Operators

+ (Unary Positive): Used to indicate a positive value; has no effect on the operand.
+ (Binary Addition): Adds two operands together.
- (Unary Negation): Changes the sign of the operand (makes it negative).
- (Binary Subtraction): Subtracts the second operand from the first.
* (Multiplication): Multiplies two operands.
/ (Division): Divides the first operand by the second. The result is always a float.
% (Modulo): Returns the remainder of a division.
// (Floor Division): Performs division and rounds the result down to the nearest integer.
** (Exponentiation): Raises the first operand to the power of the second.

Comparison Operators

== (Equal to): Checks if two operands are equal; returns True if they are, False otherwise.
!= (Not Equal to): Checks if two operands are not equal; returns True if they are not equal, False otherwise.
< (Less than): Checks if the first operand is less than the second; returns True if it is, False otherwise.
> (Greater than): Checks if the first operand is greater than the second; returns True if it is, False otherwise.
<= (Less than or equal to): Checks if the first operand is less than or equal to the second; returns True if it is, False otherwise.
>= (Greater than or equal to): Checks if the first operand is greater than or equal to the second; returns True if it is, False otherwise.

Logical Operators

not (Logical Negation): Inverts the truth value of an operand; returns True if the operand is False, and False if the operand is True.
or (Logical OR): Returns True if at least one of the operands is True, False otherwise.
and (Logical AND): Returns True if both operands are True, False otherwise.

Bitwise Operators

& (Bitwise AND): Performs a bitwise AND operation on each corresponding bit of the operands; returns 1 if both bits are 1, 0 otherwise.
| (Bitwise OR): Performs a bitwise OR operation on each corresponding bit of the operands; returns 1 if at least one bit is 1, 0 otherwise.
~ (Bitwise Negation): Flips the bits of an operand (0 becomes 1, 1 becomes 0).
^ (Bitwise XOR): Performs a bitwise XOR operation on each corresponding bit of the operands; returns 1 if the bits are different, 0 if they are the same.
>> (Right Shift): Shifts all bits in the first operand to the right by the number of positions specified by the second operand.

Membership Operators

in: Checks if a value exists within another data structure (string, list, tuple, dictionary). Returns True if it exists, False otherwise.
not in: Checks if a value doesn't exist within another data structure. Returns True if it doesn't exist, False otherwise.

Operator Precedence

Operator precedence determines the order in which operators are evaluated within an expression.
Operators with higher precedence are evaluated before operators with lower precedence.
Parentheses can be used to override precedence.

Augmented Assignment Operators

Augmented assignment operators combine an arithmetic or bitwise operation with an assignment in one step.
For example, x += 5 is equivalent to x = x + 5.
