¿Qué es el operador << en Python?

What is the << operator in Python?

They are bit shift operator which exists in many mainstream programming languages, << is the left shift and >> is the right shift, they can be demonstrated as the following table, assume an integer only take 1 byte in memory.

The left-shift operator causes the bits in shift-expression to be shifted to the left by the number of positions specified by additive-expression. A left shift is a logical shift (the bits that are shifted off the end are discarded, including the sign bit).

XOR operator in Python is also known as “exclusive or” that compares two binary numbers bitwise. If both bits are the same, XOR outputs 0. If both bits are different, XOR outputs 1. For example, when used between two integers, the XOR operator returns an integer.

To get the logical xor of two or more variables in Python:

1. Convert inputs to booleans.
2. Use the bitwise xor operator ( ^ or operator. xor )

A left shift indicates the presence of immature neutrophils in blood and usually, but not always, indicates an inflammatory leukogram (see related links for the historical origin of this term). Immature neutrophils are usually band neutrophils, but earlier forms can be seen.

A “left shift” is a phrase used to note that there are young/immature white blood cells present. Most commonly, this means that there is an infection or inflammation present and the bone marrow is producing more WBCs and releasing them into the blood before they are fully mature.

Examples: 1 XOR 1 = 0. 0 XOR 1 = 1. 0 XOR 0 = 0. 11102 XOR 10012 = 01112 (this is equivalent to addition without carry)

(eXclusive OR) A Boolean logic operation that is widely used in cryptography as well as in generating parity bits for error checking and fault tolerance. XOR compares two input bits and generates one output bit.

To find XOR of more than two numbers, represent all numbers in binary representation, add 0’s before if necessary. To find each bit of XOR just calculate number of 1’s in the corresponding bits. If it is even or zero then that XOR’ed bit is 0. If it is odd then that XOR’ed bit is 1.
