Variable

I think I am describing the variables right, but for some reason it is not working.

errors.py 
print("Hello")
print (name) 
name = 'jeff'
print("Let's do some math!")
print(5 + a) 
a = '21'
print("Thanks for playing along!")

You have to initialize the variable before you can use it; put the lines with the equals signs before the corresponding print lines. This is what you have:

print (name) 
name = 'jeff'
print("Let's do some math!")
print(5 + a) 
a = '21'

This what it needs to look like:

name = 'jeff'
print (name) 
print("Let's do some math!")
a = '21'
print(5 + a)

but your output will look something like this:

jeff

Let's do some math!

521

Edited*

I believe your last print line will throw an error, fyi.

If you need help fixing it let me know.
