""" Purpose: demonstrate assignment only effects the variable being assigned
"""
# 3 assignment statements
x = 10
y = x # the new value of y is the current value of x
x = 20 # if x changes, y does not change

# assignment statements will only change the target (on the left of the =)

print( "x:", x )
print( "y:", y )

# after line 6, x = 10 y = 10
# on line 7, we have a new assignment statement for x
# after line 7, x = 20 y = 10

# this works for python and that's what matters right now
# things will get more complicated and things get weird but for normal variables
# this will hold true for other languages
