# Variables are called this because their value can change
dollars=1.56

# All variables have a "type"
# check the type of the dollars variable:
# use the type() function to do this:
print(type(dollars))
# we saw dollars is a "float" -- which means it had a decimal point in it

print(type(governor))

# now integer type
zloty=5
# check the type of zloty
print(type(zloty))

# now an example where it can be confusing:
lei=5.0
print(type(lei))

# Question: what is the type when you add them?
newmoney=zloty+lei

# Section 2.6 -- keyboard input

# Get a user's name:
#name=input('What is your name?')
#print('Your name is',name)

#get first name
#firstname=input('What is your first name?')
#get last name
#lastname=input('What is your last name?')
# print a greeting
#print('Welcome',firstname,lastname,'!')

#this gives a type error:
#notanumber='5'
#print(3.2*notanumber)

# FACT: input always assigns a string
#hours_string=input('How many hours did you work?')
#print('The type of hours_string is',type(hours_string))
# typecasting: changing of a type
#hours=int(hours_string)
#print('The type of hours is',type(hours),'and its value is',hours)

# same but more efficient
hours=int(input('How many hours did you work?'))
