In my early days as a QA engineer / Python developer, I was working on test-related projects a lot. For such projects, the focus is on logging and the question: “How do I open a log file in Python?” comes up on a daily basis. Let’s look into possible solutions in this post.

How Do I Open A Log File In Python?

In Python, you can use the open() function to open a log file.

This function needs to know the file path and the mode (like ‘read’ or ‘write’) that you want to use.

In Python, the r mode is used to open a file in read mode.

with open('log.txt', 'r') as log_file:
    content = log_file.read()

print('content: ', content)

This means that when you open a file with this mode, you can read the data from the file, but you cannot write to it.
