Initially, we import the NumPy library and give it the alias "np" for convenience. Then, we generate a vacant array utilizing the np.array() technique and assign it to the variable named "arr". Additionally, we define a variable called "flag" to negate the output received from np.any(...

You can define a dictionary by enclosing a comma-separated series of key-value pairs in curly braces ({}). To separate the keys from their values, you need to use a colon (:). Here’s the syntax for a dictionary literal:Python Syntax { <key_1>: <value_1>, <key_2>: <value_...
