Inline operations in Python are a shorthand way of modifying a variable's value using an operator and assigning the result back to the same variable. They can be used with arithmetic, bitwise, and logical operators, and are a convenient way to update a variable's value without having to reassign it.
Here's an example of using inline operations with arithmetic operators:
x = 10x += 5 # equivalent to x = x + 5x *= 2 # equivalent to x = x * 2print(x) # Output: 30 |
In this example, the += and *= operators are used to add 5 and then double the value of x, respectively.
Here's an example of using inline operations with bitwise operators:
x = 0b1100x &= 0b1010 # equivalent to x = x & 0b1010x ^= 0b0110 # equivalent to x = x ^ 0b0110print(bin(x)) # Output: 0b0010 |
In this example, the &= and ^= operators are used to perform a bitwise AND and XOR operation, respectively, and assign the result back to x.
Here's an example of using inline operations with logical operators:
x = Truey = Falsex |= y # equivalent to x = x | yy &= x # equivalent to y = y & xprint(x, y) # Output: True False |
In this example, the |= and &= operators are used to perform a logical OR and AND operation, respectively, and assign the result back to x and y.
Inline operations can be useful when you want to update the value of a variable in a concise and readable way. However, it's important to use them judiciously and avoid writing code that is difficult to understand or maintain.
