10 commonly used python standard libraries

Python’s standard library contains a large number of modules and functions, which provide Python with rich functions and tools. The following are 10 commonly used Python standard libraries:

1. os module: Provides many functions for interacting with the operating system, such as accessing the file system, creating folders, obtaining environment variables, etc.
2. sys module: Provides functions for interacting with the Python interpreter, such as accessing command line parameters, exiting the program, obtaining Python interpreter information, etc.
3. re module: Provides regular expression-related functions and classes for matching and processing text data.
4. json module: Provides functions and classes for processing JSON format data, such as parsing JSON data into Python objects, converting Python objects into JSON data, etc.
5. datetime module: Provides functions and classes for processing date and time, such as creating date and time objects, obtaining the current date and time, calculating time differences, etc.
6. argparse module: Provides functions and classes for processing command line parameters for writing command line applications.
7. collections module: Provides many useful data structures and functions, such as Counter, OrderedDict, defaultdict, etc.
8. random module: Provides functions and classes for generating random numbers, such as generating random integers, random floating point numbers, random strings, etc.
9. itertools module: Provides many iterator-related functions and classes, such as infinite iterators, finite iterators, combined iterators, etc.
10. Logging module: Provides logging related functions and classes for tracking information, errors and debugging messages when the program is running.

These standard libraries provide many basic functions and tools for Python, allowing Python programmers to write code and process data more efficiently.
