If you need to find the longest string in a list in Python, you may be tempted to do that in the form of iterating through every element, finding their length, and checking whether this current length is larger than a temporary value that we have chosen in the beginning.

This means that we will have to implement this code using for loops, as can be seen in the example down below:

You can do that using a for loop:

There is also another quick way that you can use. This has to do with using the method max as can be seen in the following example:

This is however going to throw an error when the list does not have any element in it. To avoid that from happening, you can set the argument default to be an empty string as you can see down below:

This is much simpler and easier than the method above where we used a for-loop.

I hope you find it useful.
