...gure()
ax1 = fig1.add_subplot(111)
for i in range(1,15):
ax1.plot(np.array([1,5])*i,label=i)
The piece of code that you need:

Swift and mutating struct
...ted as either constants (via let) or variables (via var)
Consider Swift's Array struct (yes it's a struct).
var petNames: [String] = ["Ruff", "Garfield", "Nemo"]

let planetNames: [String] = ["Mercury", "Venus", "Earth", "Mars", ...
What does the brk() system call do?
...and dole it out yourself. If you keep the nodes of your binary tree in an array, you can use 8b or 16b indices instead of 64b pointers. This works great when you don't have to delete any node until you're ready to delete all the nodes. (e.g. build a sorted dictionary on the fly.) Using sbrk for ...

What is the performance cost of having a virtual method in a C++ class?
...duly hurt others.
Contrived Example: An empty virtual destructor on an array of one million small elements may plow through at least 4MB of data, thrashing your cache. If that destructor can be inlined away, the data won't be touched.
When writing library code, such considerations are far from ...
Why aren't python nested functions called closures?
...native way, as @unutbu pointed out, would be to define each variable as an array (x = [0]) and modify it's first element (x[0] += 1). Again no error arises because x itself is not modified.
5. As suggested by @raxacoricofallapatorius, you could make x a property of counter
