Take a look at the code below:

def function_1():

my_var = "Hello"

print(my_var)

def function_2():

print(my_var)

function_1()

function_2()

In this code, function_2() is attempting to print the

value of my_var. When it tries to execute the print

statement, an error generates, informing us that

'my_var' is undefined. Why does this error occur?
