Hello Sara:)

Te dejo algunas cosillas pero buen lab en general!! Poco a poco la cosa va cogiendo ritmo:) Felicidades 💥

• Convert the numbers of the following nested list to floats. Use floats as the name of the list.

flatten_list = [i for sublist in list_of_lists for i in sublist]
print(flatten_list)

Te dejo una manera de solucionarlo:) Tu approach no es del todo correcto.

• Handle the exception thrown by the code below by using try and except blocks. (division by 0)

try:
    z = x/y
except ZeroDivisionError:
    print(f"I cannot divide a number by {y}")

Tu respuesta es correcta y funciona! Solo quería que supieras que la excepción ZeroDivisionError es más especifica para este error en concreto.

• Handle the exception thrown by the code below by using try and except blocks. (index)

Idem que el ejercicio anterior pero con 'IndexError'.

Te dejo el BONUS también:

• Bonus 1

 def square_cal():
    x = input("Insert an integer to square")
    integer=False
    while integer == False:
        try:
            x= int(x)
            integer == True
            return x**2
        except ValueError as error:
            x = input(f"{error}, please insert an valid integer to square")
square_cal()

• Bonus 2

 results = list(set([num for div in range(2,10) for num in range(1,1001) if num%div == 0]))
print(results)

• Bonus 3

 class NumSectionsError(Exception):
    pass
while True:
    try:
        Total_Marks = int(input("Enter Total Marks Scored: "))
        break
    except ValueError as error:
        print(error)
while True:
    try:
        Num_of_Sections = int(input("Enter Num of Sections: "))
        if Num_of_Sections > 2:
            raise NumSectionsError
        else:
            break
    except ValueError as error:
        print(error)
    except NumSectionsError:
        print("The number of sections can't be bigger than 2") 

A por el próximo laaaaaaab! 🙌🏼
