Variables are storage locations that a user specifies before writing and running a python program. Variable names are labels of those storage locations. A variable holds a value depending on circumstances. For instance, doctor1 can be Daniel, Brenda or Rita. Patient1 can be Luke, William or Kelly. Variable names are written by adhering to rules and conventions. Rules are a must while conventions are optional but recommended as they help write readable variable names. When writing a program, you should assume that another person will examine or run it without your input and thus should be well written. The next chapter will discuss Variables. In programming, declaring variables means that we explicitly state the nature of the variable. The variable can be declared as an integer, long integer, short integer, floating integer, a string, or as a character including if it is accessible locally or globally. A variable is a storage location that changes values depending on conditions. Use descriptive names when writing your variables.
