to remove empty strings from a list of strings in python, you can use a list comprehension or the `filter()` function. here's a step-by-step tutorial to achieve this:

method 1: using list comprehension
1. define a list of strings that may contain empty strings.
2. use a list comprehension to filter out the empty strings.
3. assign the filtered list back to the original list variable.

method 2: using the `filter()` function
1. define a list of strings that may contain empty strings.
2. use the `filter()` function with a lambda function that checks if the string is not empty.
3. convert the result of `filter()` to a list using `list()`.

code explanation:
both methods utilize a condition to filter out the empty strings from the list.
the list comprehension method uses a concise syntax to create a new list without empty strings.
the `filter()` method applies the lambda function to each element and only keeps those that are not empty strings.

output:
both methods will output the list of strings with empty strings removed:

by following these methods, you can easily remove empty strings from a list of strings in python.
