Luckily, Python makes it straightforward to convert input strings into any data type needed. You can pass the input() result into a type conversion function like int(), float(), or bool() to transform it on dem
To represent one piece of data of multiple types using type hints in Python 3.10 or newer, you can use the pipe operator (|). Here’s how you’d use type hints in a function that typically returns a string containing the username but can also return None if the corresponding email ...
The function opens the file whose name is provided in its parameter. Then it applies thereadlines()method, which returns a Python list containing the lines of the file as its elements. That list is saved to thewordsvariable and returned by the function. Let’s go back to themain()function...
You can use the re module with a regular expression pattern to check if a string matches the float format.ExampleThis example demonstrates using regular expressions to match valid float patterns in strings.import re def is_float(s): pattern = r'^-?\d*(\.\d+)?$' return bool(re.match(...

As discussed, in PythonNonevalue has no length; thelenfunction does not support it. To understand it better, let’s have an example. Code example: none_val=Noneprint(type(none_val))print(len(none_val)) Output: <class 'NoneType'>TypeError: object of type 'NoneType' has no len() ...
