Why do I receive a syntax error when using "and" to declare an array in PyThon?

Question

I am learning scipy and more specifically Numpy. I wrote the following code after properly declaring an array and received the indicated error message. Would like to know why

data = np.sin(np.arange(20)).reshape(5,4)
and = data.argmax(axis=1)

Error:

File "<stdin>", line 1
and = data.argmax(axis = 1)
  ^
  SyntaxError: invalid syntax

Oh, wait, there was actually a line break there, but because you didn't code-format your code (formatting is crucial!), your code shows up as one line and gives a very different impression of what you were trying to do. — user2357112, Apr 10 '17 at 17:13
I am sorry. Did not realize the question was to post this way. A new lesson learned. Thanks. — Pythonina, Apr 10 '17 at 17:14
Don't use `and` as a variable name, it's a reserved keyword in Python — Thierry Lathuille, Apr 10 '17 at 17:15

and is a keyword in Python, used for boolean conjunction. You can't name your variables and; pick a different name.

and is a logical operator in Python, so you cannot assign something to it.

You cannot use reserved words as your variables. Pick another name like and1 maybe
