Market share of different programming languages It's difficult to provide an exact breakdown of the market share of different programming languages since the data can vary depending on the source and methodology used. However, here's a general breakdown based on some popular surveys and reports: According to the TIOBE Index, which ranks programming languages based on their popularity and usage, the top 5 programming languages as of February 2023 are: Python - 13.3% Java - 11.4% C - 9.2% C++ - 6.7% JavaScript - 2.8% The PYPL Index, which measures how often programming language tutorials are searched on Google, has a slightly different ranking as of February 2023: Python - 34.4% Java - 20.2% JavaScript - 7.4% C# - 5.8% PHP - 5.6% Both of these rankings show that Python and Java are among the most popular programming languages, with C and C++ also being widely used. JavaScript is also a popular language for web development. It's important to note that the popularity of program...

 Python NumPy NumPy (short for "Numerical Python") is a fundamental library for scientific computing in Python. It provides support for large, multi-dimensional arrays and matrices, as well as a range of mathematical functions to operate on these arrays. NumPy's key feature is its powerful "ndarray" object, which is a fast and flexible data structure for storing and manipulating large arrays of numerical data. The arrays can have any number of dimensions and are indexed by a tuple of non-negative integers. NumPy includes a wide range of mathematical functions, including element-wise operations, mathematical functions (e.g., sin, cos, exp), linear algebra, Fourier transform, and more. These operations can be applied to individual elements of an array or the entire array. NumPy is an essential library for many other data science libraries, such as Pandas and Scikit-learn. It is also a critical component for scientific computing in Python in general. To use NumPy, ...

python module & package Module A Python module is a file containing Python definitions and statements. The file name is the module name with the suffix .py appended. Within a module, the module’s name (as a string) is available as the value of the global variable __name__. Modules can define functions, classes, and variables that can be used in other Python programs. By using the import statement, you can include the definitions from a module in your program. This allows you to reuse code across multiple projects, and helps to organize your code into logical units. For example, consider the following Python module named my_module.py : def greet ( name ): print ( "Hello, " + name + ". How are you today?" ) def add ( a, b ): return a + b You can use the definitions from this module in another Python program like this: import my_module my_module.greet ( "John" ) result = my_module.add ( 3 , 4 ) print ( "3 + 4 =" , result ) This...
