    Study Notes

    Rules for Naming Variables

    • A variable name must not start with a number.
    • Avoid using spaces in variable names for better code readability.

    Allocating Data to a Variable

    • Allocating data to a variable means storing a specific value to that variable.
    • Assigning data to a variable involves storing data within that variable.

    Printing Variables

    • To print a variable within a sentence, use the + symbol to concatenate the strings and variables.
    • Adding spaces within the text when printing a variable within a sentence makes it look separate.
    • The str( ) function converts the data into a string, allowing you to print variables with different data types.

    Combining Variables

    • The + symbol in Python is used to concatenate (join together) data and information.
    • Combining variables with string statements is a common practice in Python programming.
    • Using the + symbol, you can add an integer with an age stored in a variable.

    Variables in Programming

    • A variable is a named storage location for data.
    • Variables can hold different types of data, such as values, strings, or calculations.
    • Using memorable names for variables is important for better code readability.

    The str( ) Function

    • The str( ) function converts data into a string.
    • The str( ) function can convert integer numbers into strings.
    • The str( ) function can convert numbers other than integers into strings.

    Example Code Snippet

    • The str(age) function converts the age variable to a string.
    • The print('Hello ' + name + ', you are ' + str(age) + ' years old') statement will print a sentence with the name and age.
    • The code snippet name = user INPUT() represents storing user input in the name variable.
