Python Program to Assess If a File is Closed or Not

Files in Python:

One of the most important subjects for programmers and automation testers is Python file handling (also known as File I/O). It is necessary to work with files in order to write to or read data from them.

Also, if you didn’t know, I/O operations are the most expensive processes where a programme can go wrong. As a result, you must use extreme caution while implementing file processing for reporting or any other reason. Optimizing a single file action can help in the creation of a high-performing application or a reliable automated software testing solution.

Consider the following scenario: you’re planning to construct a large Python project with a large number of workflows. Then it’s unavoidable that you don’t make a log file. You’ll also be handling the log file’s read and write activities. Debugging huge applications with log files is a terrific way to go. It’s usually better to consider a scalable design from the start, as you won’t be sorry later if you didn’t.

Given a file, the task is to assess if a given file is closed or not in Python

Program to Assess If a File is Closed or Not in Python

Below is the full approach for assessing if a file is closed or not in Python

Approach:

Make a single variable to store the path of the file. This is a constant value. This value must be replaced with the file path from your own system in the example below.
Open the file in read-only mode. In this case, we’re simply reading the contents of the file.
Check if the file is closed or not using the closed function and print the result.
Close the given file using the close() function.
Again, check if the file is closed or not using the closed function and print the result.
The Exit of Program.

Below is the implementation:

# Make a single variable to store the path of the file. This is a constant value.
# This value must be replaced with the file path from your own system in the example below.
givenFilename = "samplefile.txt"
# Open the file in read-only mode. In this case, we're simply reading the contents of the file.
file = open(givenFilename, 'r') 
# Check if the file is closed or not using the closed function and print the result.
print(file.closed)
# Close the given file using the close() function.
file.close()
# Again, Check if the file is closed or not using the closed function and print the result.
print(file.closed)

Output:

False 
True

Explanation:

The file path is stored in the variable ‘file name.’ Change the value of this variable to the path of your own file.
Dragging and dropping a file onto the terminal will show its path. The code will not run unless you change the value of this variable.
The file will be opened in reading mode. Use the open() function to open a file. The path to the file is the method’s first parameter, and the mode to open the file is the method’s second parameter.
When we open the file, we use the character ‘r’ to signify read-mode.
Here closed will return True if the file is closed else it returns False.
