A TypeError is a specific type of error raised when an operation or function is applied to an object of inappropriate type. You might encounter it in Python or JavaScript.

A TypeError often occurs during operations on two data types.

An example is given below, in which an attempt is made to add an integer to a string:

>>> 3 + "string"
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for +: 'int' and 'str'
>>>

Note that this behavior is not universal; some languages do not require two of the same data type to perform operations.

If range() is a generator in Python 3.3, why can I not call next() on a range?

Perhaps I've fallen victim to misinformation on the web, but I think it's more likely just that I've misunderstood something. Based on what I've learned so far, range() is a generator, and generators can be used as iterators. However, this…
