Python object copy example python reference Transfer

l2 = l1, then I make a series of modifications to l2, it is equivalent to directly modifying l1. This is not what I want! For example: The Code is as follows: L1 = [1, 2]L2 = l1L2.append (3)Print l1Print l2# L1 = [1, 2, 3], l2 = [1, 2, 3] This is caused by Python reference transfer. That is to say, l1 and l2 belong to the same list object. How can we get a different object? This is not so easy. Use slice to scatter, for example: The Code is as follows: L1 = [1, 2]L2 = l1 [:]L2.append (3)# L1

Question: "Why cannot I be preemptible when executing softirq ?" Answer

not introduced? In Linux, softirqd is introduced to give it a process context. 5. Note that the execution function of softirq cannot actively sleep, but it can be preemptible in softirqd. Sleep and preemption are two concepts. The former is active and the latter is passive. In addition, sleep is not allowed in softirq's processing function. It can be preemptible outside softirq and cannot be preemptible during execution. Aha, it's a bit cool to say s
