That example may not be applicable to this problem. Suggest solve this problem with loops, first, and don’t go into the comprehension solutions until that is covered in the course. Then come back and practice.
In the syntax, the expression is the value to be included in the new list, and the comprehension iterates over combinations of elements from the outer and inner iterables. You can also include an optional if statement for filtering. Let’s go through an example using list comprehension. Firs...
In this example, we will use twoforloops in list Comprehension and the final result would be a list of lists. we will not include the same numbers in each list. we will filter them using an if condition. final = [[x, y]forxin[10,20,30]foryin[30,10,50]ifx != y] print(final)...
In this line: Instead of using an intermediate list like college2, we directly filter the names from the original students list based on the second_lowest_score we found earlier. We use a list comprehension to iterate over each student in the students list and check if their score matches...
There is some debate over the effect of using deeply nested control structures upon programmer comprehension. In order to test the effect of deeply nested IF-THEN-ELSE statements, we split 148 computer science students of varing backgrounds into two groups. One group received a listing of a ...

Aren't they already cast to list though if a schema is not nested? See https://github.com/marshmallow-code/marshmallow/blob/2.x-line/src/marshmallow/schema.py#L489 Member sloria commented Mar 15, 2019 Ah, that's right. I'm still curious why the casting in Nested isn't necessary on...
The condition is evaluated, and if the condition is true, the code within the block is executed. As long as the statement is True , the rest of the code will run. The code that will be run has to be in the indented block.
for in n: The condition in thefor loopstays TRUE only if it hasn’t iterated through all the items in the iterable object(n). To better understand thefor loop, we will address several examples and finally, we shall work on a practical example. ...
I'd be happy to implement that if you'd like. The second conditional is to correct a type error that currently can happen when deserializing an iterable (such as a string) using a schema that expects a list of nested schemas. The error message attached to the exception generated in this...
