Assign variable in while loop condition in Python?
Starting Python 3.8, and the introduction of assignment expressions (PEP 572) (:= operator), it's now possible to capture the condition value (data.readline()) of the while loop as a variable (line) in order to re-use it within the body of the loop: while line := data.readline(): do_smthg(line)
How to use Python While with Assignment[4 Examples]
When it iterates at "Austin", the condition will be False because "Austin" != "Austin" will return false, and the loop will stop iterating. Python while with assignment by taking user input. Here, we will see how Python While with Assignment will work if we take user input with a while loop using the walrus operator in Python.
Python Conditional Assignment (in 3 Ways)
Python while loop multiple conditions; Python string contains substring; String Comparison in Python; Reverse string in Python; String formatting in python; Python number format; ... Python Conditional Assignment. When you want to assign a value to a variable based on some condition, like if the condition is true then assign a value to the ...

Prefer the ternary operator for simple conditional assignments. Advanced Techniques: Using short-circuit evaluation for efficiency in complex conditions. ... the term "conditional loops" might specifically refer to loops that run based on a condition. Python provides two primary types of such loops: while loop: Continues to execute as long as a ...
How To Use Assignment Expressions in Python
Python 3.8 or above. Assignment expressions are a new feature added starting in Python 3.8. ... Assignment expressions often work well in while loops because they allow us to fold more context into the loop condition. Consider the following example that embeds a user input function inside the while loop condition: while ...

How to leverage assignment expressions in Python loops?
One of the primary use cases for assignment expressions in loops is to simplify variable assignments and conditional checks. Instead of using a separate statement to assign a value and then checking it in a conditional, you can combine these steps into a single expression. For example, consider the following traditional loop:
python
Particularly with the while loop, this can remove the need to have an infinite loop, an assignment, and a condition. It also creates a smooth parallel between a loop which simply uses a function call as its condition, and one which uses that as its condition but also uses the actual value. Fork An example from the low-level UNIX world:
The Walrus Operator: Python's Assignment Expressions
Each new version of Python adds new features to the language. Back when Python 3.8 was released, the biggest change was the addition of assignment expressions.Specifically, the := operator gave you a new syntax for assigning variables in the middle of expressions. This operator is colloquially known as the walrus operator.. This tutorial is an in-depth introduction to the walrus operator.
