3,747 Pointswhat is wrong with this code? it is supposed to change the list to have only integers in it
i also tried to check isinstance() separately with every type in the list 'bool' and 'str' and still it didn't work! One more time it is related to a module in python tutorials that i need to pass in order to be able to finish studying!

3,747 Pointsmessy_list = ["a", 2, 3, 1, False, [1, 2, 3]] messy_list.insert(0, messy_list.pop(3))
Your code goes below here
for item in messy_list: if not isinstance(item, int): messy_list.remove(item)

9,300 PointsHi Ahmed,
Your next bit of code should look like this...
for item in messy_list.copy(): #<---- iterates over a copy of messy_list, this way when using "del" we won't delete indexes if type(item) != int: print(item) del messy_list[messy_list.index(item)]

1,283 Pointshi Ahmad, I think you're code should work for challenge 1
messy_list.insert(0, messy_list.pop(3))
refresh you're page and try..

1,283 Pointshi Ahmad, for the challenge 2 you can use del keyword or remove keyword. del takes the index number as an argument for example
del messy_list[0]
and the remove keyword takes the values as an argument for example
my_list = ["a","b","c",]
my_list.remove("a") # this will remove 'a' from the list
my_list.remove("b") #this will remove 'b' from the list
make sure to remember keywords syntax's
