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 program 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.

File name Property in Python:
name Property is a built-in property of the File object (IO object) in Python that is used to retrieve the file’s name from the file object.
Syntax:
fileobject.name()
Parameters: This method doesn’t accept any parameters.
Return Value:
This method’s return type is <class’str’>, and it returns the file name.
File name Property in Python with Examples
Example
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 write mode. In this case, we’re simply writing the contents into the file.
- Get the given file name using the name property and store it in a variable.
- Print the given file name.
- Close the given file using the close() function.
- 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 write mode. In this case, we're simply writing the contents into the file.
gvn_file = open(givenFilename, 'w')
# Get the given file name using the name property and store it in a variable
f_name= gvn_file.name
# Print the given file name.
print("The given file name is:", f_name)
# Close the given file using the close() function
gvn_file.close()
Output:
The given file name is: samplefile.txt
File Content:
hello this is btechgeeks good morning btechgeeks
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 ‘w’ to signify write-mode.
- We can get the file name using the name function.
