Python的for循环除了推导式中的循环变量，其它变量的作用域都会溢出

import logging

for i in range(5):
    pass
print(i)

try:
    x = [j for j in range(4)]
    print(j)
except:
    logging.exception('Not defined')
    
x = [remainder for j in range(4) if (remainder := j % 2) == 0]
print(remainder)

y = [(remainder2 := j % 2) for j in range(4)]
print(remainder2)

输出：

4
ERROR:root:Not defined
Traceback (most recent call last):....
NameError: name 'j' is not defined
