In your code, "array" is a class attribute, so it is shared among all
instances. You need to use the __init__ method to define instance
(data) attributes instead:

For what it's worth, mathematicians naturally work with angles in radians.
The mathematics of the trignonmetric functions works naturally when the
angle is expressed in radians.
For the older among us, logarithms also have a "natural" base, and that is
the number e. Back in those days, however, e
nted to the Windows Command interpreter, the spaces are
accepted as part of it without the need then of enclosing quotes.
Hope this helps.

You need to come to grip with the fact
x27;re asking is why this returns a tuple, where in the
first eval you got a string. The answer is because commas create tuples
(not parens), so:
"String1", "String2"
is a tuple expression. Whereas:

commas do.
A one element tuple is:
>>> b = ("hello,)
The parens are optional, I always put them in because:
>>> b = "hello",
The parens group an expression, they don't make a type.

Both parts, the code and the expression of your thoughts, are really
important to getting help around here :)

If you can't use pip while in the same directory as pip.exe, I don't
even know what is wrong.
That said, you can access pip via 'python -m pip args' instead of using
the pip executable.

decode it back to bytes again, probably).

Only on *nix.
Even then it varies from platform to platform which constants you can
use. I'd prefer to document the return status and use numbers/my own
constants directly, that way supporting any p
the core devs
taste and particular needs, and it goes out of its way to say that it is
only a suggestion and other concerns (especially local consistency)
override its advice.

n user error messages,
not exceptions.
Note, 1) doesn't mean I always raise a nicer message, it means if
"KeyError" is ambiguious or odd, I raise a better and more informative
one. But you're getting nothing swapping out KeyError for
Exception(lotsofwords).
I use 1) more to be less 'nicer' and more, er, 'more specific'. Since I
don't like exceptions to rise to the user level where niceness is
needed.

The r in front of the string makes it a raw string so you don't have to
double up the slashes.
