Home Python Python deque implementation Python deque is a double-ended queue. You can append to both ends and pop from both ends. The complexity of those operations amortizes to constant time. We are going to look at the Python 3 internal implementation of deques. It uses a linked list of blocks of 64 pointers to objects. This reduces memory overhead... » read more 0 Read Laurent Luce written 6 years ago Least frequently used cache eviction scheme with complexity O(1) in Python This post describes the

Functional Python Here I present a more complete script that illustrates how one can use functional python from the linux command line Using existing functional units within the script seq 100 | funcpy add Using user provided expressions This shows the flexibility of interpretation (scripts) over compilation Supported by the following construct code=compile(user_expression,"<expression>","eval") func=lambda x: eval(code) echo -e "1234\n433" | funcpy "hex(int(x))[2:]" #transform nums echo "1,2,3" | funcpy "i

Ansible Plays (Provisioning jobs) would have variables set that they inherited from other Ansible Plays, essentially if I set a variable in Play X and then ran Play Y, the variable woul
