Python finally Keyword
The Python finally keyword is used in exception handling and finally block of statement is executed regardless of try-except block results.
try: statements except: statements finally: statements
In the below example, finally block of statement is executed regardless of try-except block results, which facilitates the program to close the file before proceeding further.
MyFile = None try: MyFile = open("math_example.txt") x = MyFile.readline() y = MyFile.readline() x = x/y print(x) except: print("An error occurred.") finally: if MyFile == None: print("MyFile does not exist.") else: print("MyFile has been closed.") MyFile.close()
The output of the above code will be:
An error occurred. MyFile does not exist.
