Local variables

Local variables are the opposite. These are variables that will only work within a particular scope or code block. This means that it can only be accessed and manipulated within a certain block of code. These tend to be useful as they are automatically erased from the computer’s memory as soon as the function is finished executing. Moreover, it is a safer place to keep sensitive and private information as the variables only surface on demand. Let’s take a look at a local variable.

# This function uses global variables.

def carSale(): # This function will only run when it is called in line 7

price = 150000 # The price variable is declared locally, that means it cannot be accessed outside of the function.

print (f'Local variable price : ${price}')

carSale()

print (f '$ {price}' ) # Here is an attempt to access the variable price globally - it will produce an error -.
