The data stored in memory can be of many types. For example, a person's age is stored as a numeric value and his or her address is stored as alphanumeric characters. Python has various standard data types that are used to define the operations possible on them and the storage method for...

You define variables by assigning them a value using the assignment operator. Python variables are dynamically typed, allowing type changes through reassignment. Python variable names can include letters, digits, and underscores but can’t start with a digit. You should use snake case for multi-wor...
The recommended way to create concrete array types is by multiplying any ctypes data type with a positiveinteger. Alternatively, you can subclass this type and define _length_ and _type_ class variables. Array elementscan be read and written using standard subscript and slice accesses; for slice...
Note: Python is atype-inferredlanguage, so you don't have to explicitly define the variable type. It automatically knows thatprogramiz.prois a string and declares thesite_namevariable as a string. Changing the Value of a Variable in Python ...
You can reuse variable names by simply assigning a new value to them :>>> x = 100 >>> print(x) 100 >>> x = "Python" >>> print(x) Python >>> CopyOther ways to define valuePython allows formatting of large numbers and decimal values for better readability.>...
It’s possible to define functions inside other functions. Such functions are called inner functions. Here’s an example of a function with two inner functions:Python inner_functions.py def parent(): print("Printing from parent()") def first_child(): print("Printing from first_child()")...
