The simple answer is = is an assignment operator, == is a comparison operator. And you are wrong in saying that == can be used in any situation when = works. For example if I wanted to create the variable my_string and set it equal to "something" I would use the = operator. my_string = "something".
Nov 1, 2021 · In this lesson, we will look at the += operator in Python and see how it works with several simple examples. The operator ‘+=’ is a shorthand for the addition assignment operator. It adds two values and assigns the sum to a variable (left operand).
Run example ». Python divides the operators in the following groups: Arithmetic operators. Assignment operators. Comparison operators. Logical operators. Identity operators. Membership operators. Bitwise operators.
Jan 30, 2011 · In Python, += is sugar coating for the __iadd__ special method, or __add__ or __radd__ if __iadd__ isn't present. The __iadd__ method of a class can do anything it wants. The list object implements it and uses it to iterate over an iterable object appending each element to itself in the same way that the list's extend method does.
May 27, 2024 · Discover the essential Python operators and how to effectively use them with our comprehensive cheat sheet. We cover everything from arithmetic to bitwise operations! If you’ve ever written a few lines of Python code, you are likely familiar with Python operators.
Mar 2, 2014 · They are performing the operation and then assigning it into the variable: a += b is the same as: a = a + b. a -= b is the same as: a = a - b. a *= b is the same as: a = a * b. a /= b is the same as: a = a / b. You can use them in a while loop in the same way you would use the extended forms: i = 0. while i < 5:
May 12, 2022 · The comparison operator != compares two objects to see if they are not of the same value. It returns a boolean; if it returns True, it means that the two objects are not equal, if it returns False, it means that the two objects are equal. Some examples will illustrate the use of the != operator.
Jul 21, 2022 · This // operator divides the first number by the second number and rounds the result down to the nearest integer (or whole number). In this article, I will show you how to use the // operator and compare it to regular division so you can see how it works.
Explore Python’s comparison, Boolean, identity, and membership operators. Build expressions with comparison, Boolean, identity, and membership operators. Learn about Python’s bitwise operators and how to use them. Combine and repeat sequences using the concatenation and repetition operators.
Jan 21, 2024 · The += operator in Python is known as the 'addition assignment' operator. That's a bit of a mouthful, so let's break it down. Imagine you have a box with 5 apples in it, and you add 3 more apples to the box. Now you have a total of 8 apples.
