Procedural Programming

a classification that defines the kind of values a variable can hold and the operations that can be performed on them

A whole number, positive or negative, including zero

A positive or negative number which can have a fractional part

A value which is either true or false

A single number, letter or symbol.

A collection of characters

A way of storing memory addresses.

A collection of fields, each of which could have a different data type

A finite, indexed set of related elements each of which has the same data type.

User-defined data types are derived from existing data types in order to create a customised data structure.

Creating a variable for the first time, giving it a name and sometimes a data type. This allocates a portion of the computer’s memory to the variable.

but when creating a constant. The value of a constant does not change while the program is running.

A named block of code containing a set of instructions designed to perform a frequently used operation.

Position Returns the position of a specified character within a string.

Returns the number of characters in a specified string.

Substring Given a starting position and a length, returns a portion of a string

Joining two or more strings together to form a new, longer string

Returning the character code which corresponds to a specified character.

Returning the character represented by a given character code.

A built-in function takes a seed value and uses a series of mathematical operations to arrive at a number

import random random_integer = random.randint(1, 10) print(random_integer)

Procedure dosent always returns a vlue function always returns a value

A local variable is a variable that can only be accessed from the subroutine within which it is declared. It is memory efficient

global variables can be accessed from any part of a program and exist in memory for the entire duration of the program’s execution.
