What is a lambda function?
Lambda functions in Python are anonymous functions that are defined without a name. They are often used when a function is required for a short period of time, such as in a loop or as a callback function. However, when using lambda functions in a loop, it is common to encounter an issue where all of the lambda functions seem to return the same result, regardless of the different values that are passed to them. This behavior can be confusing and frustrating for programmers, especially if they are not aware of the underlying mechanisms behind lambda functions.
Why do Python lambda defined in a loop with different values all return the same result?
In this article, we are going to learn why Python lambda defined in a loop with different values all return the same result.
In this article, we will explore the reasons behind this behavior and discuss how to avoid it. We will start by looking at how lambda functions are defined and executed, and how they capture the values of variables that are used within their body. We will then look at an example of how this can cause lambda functions defined in a loop to all return the same result, and finally, we will discuss how to avoid this issue by using default argument values instead of closing over variables.
