6. There are multiple libraries available for Python, like numpy, pandas, etc., to make doing complex operations easy!
### Cons
1. Being open source, many different ways have developed over the year for same function. This sometimes, creates chaos for others to read someone else code.
2. It is a slow language. So, a very bad language to use for developing general algorithms.
3. Python is not the best langauge to use if your project requires efficient memory management.

- Python is dynamically typed, so the errors in code only show up after running an application.

A function is called when the name of the function is followed by `()`. For the 'Hello, World!' example, the print function is called with a string as an argument for the first parameter. For the rest of the parameters the defaults are used.

The argument that we called the `print` function with is a `str` object or _string_, one of Python's <a href='https://docs.python.org/3/library/stdtypes.html#text-sequence-type-str' target='_blank' rel='nofollow'>_built-in types_</a>.
The argument that we called the `print` function with is a `str` object or _string_, one of Python's [_built-in data types_](https://docs.python.org/3/library/stdtypes.html#text-sequence-type-str).
Also the most important thing about python is that you don't have to specify the data type while declaring a variable, python's compiler will do that itself based on the type of value assigned.
The `objects` parameter is prefixed with a `*`, which indicates that the function will take an arbitrary number of arguments for that parameter.
