Remove Elements From A Counter

 

counter에서 요소 삭제하기

Question:

How do you remove an element from a counter?

Answer:

Setting a count to zero does not remove an element from a counter. Use del to remove it entirely.

Source: (example.py)

from collections import Counter
 
c = Counter(x=10, y=7, z=3)
print(c)
 
c['z'] = 0
print(c)
 
del c['z']
print(c)

Output:

$ python example.py
Counter({'x': 10, 'y': 7, 'z': 3})
Counter({'x': 10, 'y': 7, 'z': 0})
Counter({'x': 10, 'y': 7})
