Deep Learning: Practical Tips for Reading .py Files in Python

Methods for reading .py files in Python include: using the open() function to open the file and read the content. Use importlib.machinery to load the script file and obtain its code object.

In-depth learning: Practical tips for reading .py files in Python

Reading Python scripts Files (.py files) are a necessary part of many programming tasks. This article delves into various techniques for reading .py files using Python and provides some practical examples.

Method 1: Using the open() function

with open('myfile.py', 'r') as file:
    code = file.read()

This method opens the file for reading and then stores the file contents in code variable.

Method 2: Use importlib.machinery

import importlib.machinery

loader = importlib.machinery.SourceFileLoader('myfile', 'myfile.py')
code = loader.get_code('myfile')

This method uses importlib.machinery to load the script file and get its code object.

Practical case:

Read and print the function in the .py file

with open('myfile.py', 'r') as file:
    code = file.read()
    exec(code)

print(my_function())

This code will read the myfile.py file, execute the included code, and call the my_function() function.

Load and execute the classes in the .py file**

import importlib.machinery

loader = importlib.machinery.SourceFileLoader('myfile', 'myfile.py')
code = loader.get_code('myfile')
exec(code)

my_class = My_Class()
my_class.my_method()

This code will load the myfile.py file and execute the included code, And create an instance of the My_Class class.
