When I run ```eliminate_elements([['N','L'],['G','N',['N','B']],'L'])```,I want the output to be ```[[],[,['B']]``` Why is 'L' not removed when it clearly is an element in to_eliminate?
Please note that I do not want built in python functions to do this,I have to create my own function that does not rely on any outside modules or functions.
# your code goes here
def eliminate_elements(my_list,to_eliminate):
'''
To complete.
'''
for sub_list in my_list:
for i in to_eliminate:
if i in sub_list:
occu = sub_list.count(i)
for _ in range(occu):
sub_list.remove(i)
return my_list
print(eliminate_elements( [['N','L'],['G','N',['N','B']],'L']))
输出
[[],['G'],['B']]
