Hello León:)

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

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

sqrt = list(map(lambda x: math.sqrt(x), range(1,101)))
sqrt

Te pide la raíz cuadrada los 100 primeros números, en tu rango especificas range(0,21) 🫠 pequeño despiste jeje

• Find all of the numbers from 1-1000 that are divisible by 7. Use divisible_by_seven as the name of the list.

divisible_by_seven = [x for x in range(1,1001) if x%7 == 0]
print(divisible_by_seven)

Te pide los números divisibles entre 7 de 1-1000, en tu rango especificas range(1, 101) 🫠 pequeño despiste jeje

• 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 = "aeiouAEIOU"
non_vowels = [i for i in teststring if i.lower() not in vowels and i != ' ']
print(non_vowels)

Tu código es OK!! Te dejo otra manera de hacerlo para que no tengas que importar el módulo de 'functools'.

• Find the folders you have in your lectures local repo. Use files as name of the list.

path = "../../lectures"     -- your path here:)
files = [os.listdir(path)]

from os import listdir
filenames = [f for f in listdir(path)]
print(filenames)

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

random_lists = [[random.randrange(n,101) for n in range(0,10)] for i in range(0,5)]
print(random_lists)

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. (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! 💥
