Challenge Task 2 of 3 Question

Question asks: Use .remove() and/or del to remove the string, boolean, and list members of the_list.

This seems to work for me in the terminal. Is this wrong?

 the_list = ["a", 2, 3, 1, False, [1, 2, 3]]

# Your code goes below here

crap = the_list.pop(3)
the_list.insert(0, crap)
print(the_list)

length = len(the_list)
for i in range(0, length):
    i = 0
    del the_list[i]
    i += 1

print(the_list)

the_list = ["a", 2, 3, 1, False, [1, 2, 3]]

Your code goes below here

the_list.insert(0, the_list.pop(3)) print the_list

for i in range(0, len(the_list)): try: del the_list[0] except IndexError: pass print the_list

This is my solution to the problem.

Another way is to use the reverse() function on the list and iterate through it backwards.

the_list = ["a", 2, 3, 1, False, [1, 2, 3]]
temp_list = []

for item in the_list:
    if type(item) == int:
        temp_list.append(item)

the_list = temp_list

print the_list

Hi Chris Bennett

Thanks for the help!

Maybe I am misunderstanding the question. I interpreted it as "Delete all items in the list". Is this incorrect? What is "and list members of the_list" referring to?

Thanks!

It is asking you to basically delete everything that isn't an int from the list (the boolean, string and list objects).

At the end of "the_list" (list[5]) is a list, that needs to be deleted. The wording is a bit confusing.

You can see what types things are by using the type() function. type(the_list[5]) would return list.
