python list remove multiple elements code example

Example 1: python remove multipl eelements from list

unwanted = {'item', 5}
item_list = [e for e in item_list if e not in unwanted]

Example 2: remove one value from list more than once

# list with integer elements
list = [10, 20, 10, 30, 10, 40, 10, 50]
# number (n) to be removed
n = 10

# print original list 
print ("Original list:")
print (list)

# loop to traverse each element in list
# and, remove elements 
# which are equals to n
i=0 #loop counter
length = len(list)  #list length 
while(i<length):
	if(list[i]==n):
		list.remove (list[i])
		# as an element is removed	
		# so decrease the length by 1	
		length = length -1  
		# run loop again to check element							
		# at same index, when item removed 
		# next item will shift to the left 
		continue
	i = i+1

# print list after removing given element
print ("list after removing elements:")
print (list)
