Remove all occurrences in List using While Statement
customerlistids = [21, 5, 8, 52, 21, 87] c_detail = 21 while c_detail in customerlistids: customerlistids.remove(c_detail) print(customerlistids)
Example 2: Remove all occurrences in List using Filter
customerlistids = [21, 5, 8, 52, 21, 87] c_detail = 21 #delete the item for all its occurrences customerlistids = list(filter((c_detail).__ne__, customerlistids)) print(customerlistids)

customerlistids = [21, 5, 8, 52, 21, 87] c_detail = 21 #remove the item for all its occurrences for item in customerlistids: if(item==c_detail): customerlistids.remove(c_detail) print(customerlistids)
There are 3 Examples for remove all occurrences of a character in a list python.
1. Using list.remove() function
if __name__ == '__main__':
l = [0, 1, 0, 0, 1, 0, 1, 1]
val = 0
l.remove(val)
print(l) # prints [1, 0, 0, 1, 0, 1, 1]
2. Using List Comprehension
if __name__ == '__main__':
l = [0, 1, 0, 0, 1, 0, 1, 1]
val = 0
# filter the list to exclude 0's
l = [i for i in l if i != val]
print(l) # prints [1, 1, 1, 1]
3. Using filter() function
if __name__ == '__main__':
l = [0, 1, 0, 0, 1, 0, 1, 1]
val = 0
l = list(filter(lambda x: x != val, l))
print(l) # prints [1, 1, 1, 1]
That’s all about removing all occurrences of an element from a list in Python example.
