# x = 10
# cs151 = 5
# myNiceVariableName = 1
# print(x)
# print(myNiceVariableName)

# another_var_name = 99
# print(another_var_name)

# cs151 = 50 
# 50 = cs151 # variable name being assigned TO needs to be on the LEFT

# cs151 = 50
# x = 9
# print(cs151)

# cs151 = -99
# print(cs151)

# x = 3
# y = 4
# z = x + y # just like z = 3 + 4
# print(z)

# to use variables on the, right you need to assign a value first!
# z + x + y + a
# print(z)

# assigning a variable to another variable
a = 1
b = 2
a = b
# Now I change b
b = 9
# What happens to a and b?
print(a) # 9? 2? <- actually is 2, not 9
print(b) # 9! <- checks out!

# a started as 1. Assigned it to the value of b (2). Changed b to 9, yet a remains 2.

n = 3
cs151 = 'hi!'
print(n*cs151) # python replaces values: 3*'hi!'
print(m*cs151) # m not in symbol, will not work. Need to define m before using it.
