What type of programming language is python?

Python is a computer programming language and an object-oriented, dynamic, strongly typed scripting language (interpreted language).

• Strong type: Do not allow addition of different types

• Dynamic type: Do not use explicit data type declaration, and determine the type of a variable is When assigning a value to it for the first time

• Script language: It is generally an interpreted language. At the moment before the program is run, there is only the source program and no executable program; and every time the program executes a certain instruction of the source program, the interpreter converts the source code into binary code for execution; in short, it is continuous interpretation and execution , interpretation, execution....

Strongly typed language and weakly typed language

1. Strongly typed language: Make it mandatory Type definition language. Variables of two different types are not allowed to operate with each other without forced type conversion. Strongly typed definition languages ​​are type-safe languages, such as Java, C# and python. For example, "int i = 0.0;" in Java cannot be compiled;

2. Weakly typed languages: data types can be ignored language. Contrary to strongly typed languages, a variable can be assigned values ​​of different data types, allowing a piece of memory to be treated as multiple types, such as directly adding integer variables and character variables. C/C and PHP are both weakly typed languages. For example, "int i = 0.0;" in C can be compiled and run.

Static and dynamically typed languages

static and dynamic are for the data type of the variable. The difference is as follows:

1. In code written in a statically typed language, the data type of the variable must be declared, and variables of different data types are not allowed to be directly assigned. Its data type is checked during compilation.

2. Before using variables in statically typed languages, you need to allocate memory for them.

3. Static type languages ​​are powerful, but relatively difficult to learn and have poor flexibility.

4. Dynamic type language is just the opposite of static language. It only checks the data type during the running of the program. There is no need to specify a data type for the variable. It will check the data type when a colleague assigns the variable for the first time. Internal record data type.

5. Although dynamically typed languages ​​are fast and flexible, it is difficult to find bugs before the code is run. Therefore, the development speed is improved, but the robustness of the program is lost.

1) Static type languages: c, c, c#, object-c, Java, etc.

2) Dynamic type languages: Python, ruby, PHP, JavaScript, erlang, etc.
