Write mode ('w'): This mode is used to write to a file. It will create a new file if the file does not exist, and overwrite the file if it does exist. Append mode ('a'): This mode is used to add new data to the end of an existing file (append to a file). If the file...

self.file.seek(0) ... return json.load(self.file) ... You’ll notice two things. First, unlike .__copy__(), this method takes an argument, which must be a Python dictionary. It’s used internally by Python to avoid infinite loops when it recursively traverses reference cycles. Sec...
In a Python file, this will be declared at the top of the code, under any shebang lines or general comments. So, in the Python program filemy_rand_int.pywe would import therandommodule to generate random numbers in this manner:
