Needing assistance to figure out how to remove anything but integers from modified list. Not sure where my code is going wrong. Thanks in advance!
messy_list = ["a", 2, 3, 1, False, [1, 2, 3]]
# Your code goes below here
cleaner_list = messy_list.insert(0,messy_list.pop(3))
for item in cleaner_list:
if item = int(item):
pass
else:
cleaner_list.remove(item)

messy_list = ["a", 2, 3, 1, False, [1, 2, 3]]
Your code goes below here
first part of objective code
messy_list.insert(0,messy_list.pop(3))
create empty list for integer only assignment
cleaner_list = []
iterate through messy_list
for e in messy_list:
###remove from messy_list if type is NOT an integer
if type(e) != int:
messy_list.remove(e)
###append to empty list if type IS an integer
else:
cleaner_list.append(e)
reset messy_list to integer only cleaner_list
messy_list = cleaner_list
