      • Because Python uses indentation for code evaluation, it needs to keep track of the level of indentation across code blocks.

      • In Python, the term “object” is quite the catch-all; including numbers, strings of characters, lists, functions - a Python object is essentially anything that you can assign to a variable. That being said, there are different types of objects: Python treats integers as a different type of object than a string, for instance.
      • Python lists have a built-in sort() method that modifies the list in-place and a sorted() built-in function that builds a new sorted list from an iterable..

Moreover, a number of special-purpose Python objects act "file-like" without quite being files; for example, gzip.open() and urllib.urlopen() .
      • As I read it, the description says it is giving you an array of strings and non-negative numbers. It asks to filter out the strings but it does not ask to filter out negative numbers. It simply specifies that it won't be giving you any negative numbers. So I took this to mean, don't worry about negative numbers because they aren't a factor.

Python is an open-source programming language used by beginners for its easy-to-read code and experts for its substantial libraries and ability to add modules from other programming languages such as C. When programming in Python, you may need to convert an integer or a string to a floating point number, or float. COBOL has the intrinsic functions TEST-NUMVAL and TEST-NUMVAL-C to check if a string is numeric (TEST-NUMVAL-C is used to check if it is also a monetary string). Implementations supporting the 20XX draft standard can also use TEST-NUMVAL-F for floating-point numbers. They return 0 if the string is valid, or the position of the first incorrect ...

Oct 17, 2003 · The Decimal data type will support the Python standard functions and operations, and must comply with the decimal arithmetic ANSI standard X3.274-1996 . Decimal will be floating point (as opposed to fixed point) and will have bounded precision (the precision is the upper limit on the number of significant digits in a result).
