The hasext()
function is a built-in Python function that checks if a given file path has a certain file extension. This function is commonly used in Python programs for file handling and manipulation.
The syntax of hasext()
is as follows:
def hasext(filename, extension)
The hasext()
function accepts two parameters:
filename
: The file path to be checked for the presence of a certain file extension.extension
: The file extension to be checked for. This parameter should be a string, with or without the leading dot (e.g. "txt" or ".txt").The hasext()
function returns a boolean value. It returns True
if the given file path has the specified file extension, and False
if it does not.
The following code snippet demonstrates an example usage of hasext()
:
filename = "/path/to/myfile.txt"
if hasext(filename, "txt"):
print("The file has the .txt extension.")
else:
print("The file does not have the .txt extension.")
In the above code, we first define a variable filename
that holds the path to our file. We then use hasext()
to check if the file has the .txt extension, and print a message accordingly.
In summary, the hasext()
function is a useful built-in Python function that checks if a given file path has a certain file extension. It is an important tool for developers who work with file manipulation in Python, and can help automate and simplify many file-handling tasks.
