Given a list, and we have to remove all occurrences of a given element from the list in Python.

Example:

    Input:
    list = [10, 20, 10, 30, 10, 40, 10, 50]
    n = 10

    Output:
    list after removing 10 from the list
    list = [20, 30, 40, 50]

Logic:

• Traverse each number in the list by using for...in loop.
• Check the element whether it is equal to the number (which is to be removed) or not.
• If any element of the list is equal to the number (which is to be removed), remove that element from the list.
• To remove the number from the list, use list.remove() method.

Example:

# list with integer elements
list = [10, 20, 10, 30, 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
for i in list:
	if(i==n):
		list.remove (i)

# print list after removing ODD elements 
print "list after removing ODD elements:"
print list

Output

    Original list:
    [10, 20, 10, 30, 40, 10, 50]
    list after removing ODD elements:
    [20, 30, 40, 50]
