How to analyze the animated demonstration of Lambda function

How to analyze the animation demonstration of Lambda function, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Some readers reported that the lambda function is not very good at using, and asked if they could explain it.

For example, the following lambda function:

Def max_len (* lists):

Return max (* lists, key=lambda v: len (v))

There are the following doubts:

What is the value of parameter v? Does the lambda function have a return value? If so, what is the return value?

The above function finds the longest of the three lists:

R = max_len ([1,2,3], [4,5,6,7], [8])

Print (the longer list of f' is {r}')

The complete execution of the code is demonstrated in the animation as follows:

Conclusion:

The value of the parameter v is the element of the lowest tuple in the diagram.

The return value of the lambda function is equal to the return value of the expression after the lambda v colon.

This is the answer to the animation demonstration question on how to analyze the Lambda function. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
