Consider the following Python code:

a = 7
g = lambda x: a * x
a = 2
g(10)

1. What is the result of evaluating the Python code?

20

2. Convert the code to an expression in the Lambda Calculus

$$(\lambda a . (\lambda g . (\lambda x . a * x)g)10)2$$

3. Write an equivalent Python expression using the lambda keyword

g = lambda a: lambda x: lambda: a * x
g(10)(2)()

4. What is the result of evaluating the Python expression?

In[0] : g(10)(2)()
Out[0]: 20

5. What accounts for the difference between (1) and (4)?

Both results are 20.
