Why doesn't Python have a sign function?
...didn't agree on what it should return in all the edge cases (+/-0, +/-nan, etc)
So they decided to implement only copysign, which (although more verbose) can be used to delegate to the end user the desired behavior for edge cases - which sometimes might require the call to cmp(x,0).

class Wizard:
def __init__(self, argv):

// arr[1] == 5
return 0;
}

this.
int * fillarr(int arr[], int length)

That means it's possible that tools installed prior to using Homebrew may have created /usr/local such that it can't be modified without sudo. They don't discuss that at the w...

What is the difference between Class and Klass in ruby?
..., so you won't be able to have variables named def or module or if or end, etc - class is no different.
For example, consider the following:
def show_methods(class)
