Hello Victor:)

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

• Calculate the square number of the first 20 numbers. Use square as the name of the list.

square = [i**2 for i in range(21)]
print (square)

Si quieres incluir el cuadrado de 20 en la lista, debes ajustar el rango a 21!

• Calculate the square root of the first 100 numbers. Use sqrt as the name of the list.

sqrt = [math.sqrt(i) for i in range(101)]
print (sqrt)

Idem que en el ejercicio anterior:) Si quieres incluir el cuadrado de 100 en la lista, debes ajustar el rango a 101!

• Remove all of the vowels in a string. Hint: make a list of the non-vowels. Use non_vowels as the name of the list.

vowels = ["a", "e", "i", "o", "u", "A", "E", "I", "O", "U"]
removed = ([i for i in teststring if i not in vowels and i != ' '])

print (removed)

Correctísima tu respuesta! Solo te dejo un pequeño tip para hacerlo de otra manera:) Si añades and i != ' ' en tu comprehension list, también eliminarás los espacios en blanco y estarás devolviendo una lista. Haciendo "".join estas devolviendo una string.

• Create 4 lists of 10 random numbers between 0 and 100 each. Use random_lists as the name of the list.

random_lists = [[random.randint(0, 101) for l in range(4)] for i in range(10)]
print (random_lists)

Pequeño despiste, jeje. Te pide 4 listas dentro de una lista:) En tu código estas generando solo una lista. Si incluyes random.randint(0, 101) for l in range(4) entre [], lo tienes!!!!!!

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

for i in ['a','b','c']:
    try:
        print (i**2)
    except:
        print(f"I cannot square the element of your list {i}")

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! 💥
