Exercise 5

Make a code cell below
declare the variable dash='\n----------' and print it
declare your own variables to contain the following values, trying to use a range of allowed names
```
    1, 2, 'one', 'hello world', '1\n2\n3\t 4 5 6\n😀, 我在这里'
```
print the variables to see if they contain what you expect, followed in each instance by dash (to space the answers out)

# ANSWER

# Make a code cell below
# declare the variable dash='\n----------' and print it
dash='\n----------'
print(dash)

# declare your own variables to contain the following values, trying to use a range of allowed names
#      1, 2, 'one', 'hello world', '1\n2\n3\t 4 5 6\n😀, 我在这里'

avar = 1
bvar = 2
one = 'one'
Hello = 'hello world'
string_thing = '1\n2\n3\t 4 5 6\n😀, 我在这里'

#print the variables to see if they contain what you expect, followed in each instance by dash (to space the answers out)
print(avar,dash)
print(bvar,dash)
print(one,dash)
print(Hello,dash)
print(string_thing,dash)
