为什么解压会删除obj的内容

Question

有人能向我解释一下，为什么解压压缩对象（z1）会使初始对象（z1）为空

mutants = ['charles xavier', 'bobby drake',
           'kurt wagner', 'max eisenhardt', 'kitty pride']
powers = ['telepathy', 'thermokinesis',
'teleportation', 'magnetokinesis', 'intangibility']

z1 = zip(mutants, powers)

print(*z1)

print(*z1)

Answer 1

线程ID是唯一的；但您需要注意，一旦线程终止，JVM可能会重用线程ID
