- 1. Python is high level general purpose programming language Python is considered as one of the most popular programming language Python is commonly used for developing o Web application o Desktop Application o Data analysis o AI & ML
- 2. It is developed by Guido Van Rossum It is developed in 1991 It is crated at Center For Mathematics and Research in Netherland It is inspired by another programming language called ABC
- 3. The name Python is inspired from Guido’s favorite Comedy TV show called “Monty Python’s Flying Circus” Guido wanted a name that was short, unique, and slightly so he decided to call the language Python.
- 4. There are many examples of popular and high-load websites have been developed using Python. Here are some of the most popular of them NASA Instagram Udemy Spotify Mozilla
- 5. Simple and easy to learn Dynamically Typed language Object oriented programming language High level language Interpreted based language Free and open source GUI based programming language Huge Library
- 6. Python is very easy to learn as compared to other programming language It syntax is straightforward and the same as the English language There are no semicolon and curly-bracket The indentation defines the code block Python code is comparatively 3 to 5 times smaller than C/C++/Java code
- 7. In c language #include int main() { printf("Hello World"); return0; } In java public class HelloWorld{ public static void main(String[] args ) { System.out.println( "Hello World "); } } IN PYTHON print('Hello world !')
- 8. In Python, we don't need to specify the data-type of the variable. When we assign some value to the variable, it automatically allocates the memory to the variable at run time. Suppose we are assigned integer value 10 to x, then we don't need to write int x = 10 Just write x = 10
- 9. Static type ( c c++ java) Dynamic type python 1. Need to declare variable type before using it 1. Do not need to declare variable type 2. Can not change variable type at run time 2. Can change variable type at runtime 3. Variable can hold only one type of value for lifetime 3. Variable can hold different type of value for lifetime
- 10. Local variable Global variable The variables that are declared inside a function are called local variables. These types of variables can be accessed only inside the function. The variables that are declared outside the function are called global variables. These variables can be accessed or invoked by any function in the program. def f(): s = “Hello World" print("Inside Function:", s) f() print(s) def f(): print("Inside Function", s) s = “Hello world" f() print("Outside Function", s)
