Python is a powerful general-purpose programming language. Python Programming Language is pretty good suited for Beginners, Experienced programmers with other programming languages like C++ and Java.

Facts about Python Programming Language

Here are some important & interesting facts of python programming language that must be aware of beginners and experienced candidates:

Currently, Python programming is the most extensively used multi-purpose, high-level programming language.
Python permits programming in Object-Oriented and Procedural paradigms.
Python programs commonly are smaller than other programming languages similar to Java. Programmers have to type relatively less and the indentation requirement of the language makes them readable all the time.
All almost all tech-giant companies like – Google, Amazon, Facebook, Instagram, Dropbox, Uber… etc. used the Python language.
The biggest strength of Python is its huge collection of standard library which can be utilized for the following:
- Test Frameworks
- Machine Learning
- Scientific computing
- GUI Applications (like Kivy, Tkinter, PyQt, etc.)
- Image processing (like OpenCV, Pillow)
- Web frameworks like Django (used by YouTube, Instagram, Dropbox)
- Web scraping (like Scrapy, BeautifulSoup, Selenium)
- Multimedia
- Text processing and many more.

11 Beginner Tips to Learn Python Programming Language

Python Dictionary Methods

Methods that are available with a dictionary are listed below with a brief description:

Method	Description
clear()	Delete all items from the dictionary.
copy()	Returns a shallow copy of the dictionary.
fromkeys(seq[, v])	Returns a new dictionary with keys from `seq` and value equal to `v` (defaults to `None`).
get(key[,d])	Write the value of the `key`. If the `key` does not exist, returns `d` (defaults to `None`).
items()	Return a new object of the dictionary’s items in (key, value) format.
keys()	Gives a new object of the dictionary’s keys.
pop(key[,d])	Eliminate the item with the `key` and returns its value or `d` if `key` is not found. If `d` is not provided and the `key` is not found, it raises `KeyError`.
popitem()	Removes and returns an arbitrary item (key, value). Raises `KeyError` if the dictionary is empty.
setdefault(key[,d])	Returns the corresponding value if the `key` is in the dictionary. If not, inserts the `key` with a value of `d` and returns `d` (defaults to `None`).
update([other])	Updates the dictionary with the key/value pairs from `other`, overwriting existing keys.
values()	Returns a new object of the dictionary’s values

Dictionary Built-in Functions in Python

Built-in functions such as all(), any(), len(), cmp(), sorted(), etc. are generally used with dictionaries to run different tasks.

Function	Description
all()	Return `True` if all keys of the dictionary are True (or if the dictionary is empty).
len()	Return the length (the number of items) in the dictionary.
any()	Return `True` if any key of the dictionary is true. If the dictionary is empty, return `False`.
sorted()	Return a new sorted list of keys in the dictionary
cmp()	Compares items of two dictionaries. (Not available in Python 3)

Python Set Methods with Descriptions

In Python Set programs, beginners need to understand & learn how many set methods and what are their uses. Some of the python set methods are listed here with the set objects for a better understanding of the concepts:

Method	Description
add()	Adds an element to the set
clear()	Removes all elements from the set
copy()	Returns a copy of the set
difference()	Returns the difference of two or more sets as a new set
difference_update()	Removes all elements of another set from this set
discard()	Removes an element from the set if it is a member. (Do nothing if the element is not in Set)
intersection()	Returns the intersection of two sets as a new set
intersection_update()	Updates the set with the intersection of itself and another
isdisjoint()	Returns `True` if two sets have a null intersection
issubset()	Returns `True` if another set contains this set
issuperset()	Returns `True` if this set contains another set
pop()	Removes and returns an arbitrary set element. Raises `KeyError` if the set is empty
remove()	Removes an element from the set. If the element is not a member, raises a `KeyError`
symmetric_difference()	Returns the symmetric difference of two sets as a new set
symmetric_difference_update()	Updates a set with the symmetric difference of itself and another
union()	Returns the union of sets in a new set
update()	Updates the set with the union of itself and others

Built-in Functions of Python Set Operations Programs

To perform and execute various tasks in set programs, some of the built-in functions like all(), any(), enumerate(), len(), max(), min(), sorted(), sum() etc. are used with sets in python programming language.

Function	Description
all()	Returns `True` if all elements of the set are true (or if the set is empty).
any()	Returns `True` if any element of the set is true. If the set is empty, returns `False`.
enumerate()	Returns an enumerate object. It contains the index and value for all the items of the set as a pair.
len()	Returns the length (the number of items) in the set.
max()	Returns the largest item in the set.
min()	Returns the smallest item in the set.
sorted()	Returns a new sorted list from elements in the set(does not sort the set itself).
sum()	Returns the sum of all elements in the set.
