Type 2. Value - By changing the type of a value, the size of the allocated memory is also changed. - We have to use the TypeCode to define its type in an array. #2 - Normal integers go from a negative range to a positive range. - Unsigned integers are used when you do not want to store negative values. - A numeric variable is signed if it can represent both positive and negative numbers. - A value will be unsigned if it can only represent non-negative numbers (zero or positive numbers). #3 - buffer info() function gives you the size of an array. - buffer info() function returns two things: an address and the size of an array. - typecode () function is used to return the type code of an array with which you are working. - append() method is used to add a value in an integer. - remove() method is used to remove a value from an array. - reverse() method is used to reverse the order of value of an array. #4 - In python, arrays also support indexing. Values can be fetched through index values. - Array indexing is the same as accessing an array element. - You can access an array element by referring to its index number. - len() function is used to get the length or size of an array. - len() function returns the number of elements present in the array. - We can use both for loop and while loop in different ways to fetch the values of an array. - We can also assign all values of a previous array into a new array one by one.
