Operadores de Python
Operadores de Python
Los operadores se utilizan para realizar operaciones en variables y valores.
En el siguiente ejemplo, usamos el +operador para sumar dos valores:
Ejemplo
print(10 + 5)
Python divide a los operadores en los siguientes grupos:
- Operadores aritméticos
- Operadores de Asignación
- Operadores de comparación
- Operadores logicos
- Operadores de identidad
- Operadores de membresía
- Operadores bit a bit
Operadores aritméticos de Python
Los operadores aritméticos se utilizan con valores numéricos para realizar operaciones matemáticas comunes:
| Operator | Name | Example | Try it |
|---|---|---|---|
| + | Addition | x + y | |
| - | Subtraction | x - y | |
| * | Multiplication | x * y | |
| / | Division | x / y | |
| % | Modulus | x % y | |
| ** | Exponentiation | x ** y | |
| // | Floor division | x // y |
Operadores de asignación de Python
Los operadores de asignación se utilizan para asignar valores a las variables:
| Operator | Example | Same As | Try it |
|---|---|---|---|
| = | x = 5 | x = 5 | |
| += | x += 3 | x = x + 3 | |
| -= | x -= 3 | x = x - 3 | |
| *= | x *= 3 | x = x * 3 | |
| /= | x /= 3 | x = x / 3 | |
| %= | x %= 3 | x = x % 3 | |
| //= | x //= 3 | x = x // 3 | |
| **= | x **= 3 | x = x ** 3 | |
| &= | x &= 3 | x = x & 3 | |
| |= | x |= 3 | x = x | 3 | |
| ^= | x ^= 3 | x = x ^ 3 | |
| >>= | x >>= 3 | x = x >> 3 | |
| <<= | x <<= 3 | x = x << 3 |
Operadores de comparación de Python
Los operadores de comparación se utilizan para comparar dos valores:
| Operator | Name | Example | Try it |
|---|---|---|---|
| == | Equal | x == y | |
| != | Not equal | x != y | |
| > | Greater than | x > y | |
| < | Less than | x < y | |
| >= | Greater than or equal to | x >= y | |
| <= | Less than or equal to | x <= y |
Operadores lógicos de Python
Los operadores lógicos se utilizan para combinar sentencias condicionales:
| Operator | Description | Example | Try it |
|---|---|---|---|
| and | Returns True if both statements are true | x < 5 and x < 10 | |
| or | Returns True if one of the statements is true | x < 5 or x < 4 | |
| not | Reverse the result, returns False if the result is true | not(x < 5 and x < 10) |
Operadores de identidad de Python
Los operadores de identidad se utilizan para comparar los objetos, no si son iguales, sino si en realidad son el mismo objeto, con la misma ubicación de memoria:
| Operator | Description | Example | Try it |
|---|---|---|---|
| is | Returns True if both variables are the same object | x is y | |
| is not | Returns True if both variables are not the same object | x is not y |
Operadores de membresía de Python
Los operadores de membresía se utilizan para probar si una secuencia se presenta en un objeto:
| Operator | Description | Example | Try it |
|---|---|---|---|
| in | Returns True if a sequence with the specified value is present in the object | x in y | |
| not in | Returns True if a sequence with the specified value is not present in the object | x not in y |
Operadores bit a bit de Python
Los operadores bit a bit se utilizan para comparar números (binarios):
| Operator | Name | Description |
|---|---|---|
| & | AND | Sets each bit to 1 if both bits are 1 |
| | | OR | Sets each bit to 1 if one of two bits is 1 |
| ^ | XOR | Sets each bit to 1 if only one of two bits is 1 |
| ~ | NOT | Inverts all the bits |
| << | Zero fill left shift | Shift left by pushing zeros in from the right and let the leftmost bits fall off |
| >> | Signed right shift | Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off |
