What is the value of y when this code executes?

def foo (x):

if x > = 0:

return 6 * x

y = foo (-10)

y = None

y = 60

y = - 60

y = 20

The operation of 6*x only executes if x is greater or equal to 0, since x=-10 and - 10 is less than 0, the operation does not execute. For this reason, the value of y using this code is None.

Explanation:

In python a function is defined with the syntaxis:

def function (x):

the operation to execute (x)

value to return

In this case, the function is foo and the parameter is x:

def foo (x):

if x> = 0:

return 6*x

The code starts by assigning a value to x. Then, the code asks if the value of x is grater or equal to 0, if this condition is meet, then the code returns the value of 6 times x, if not, then the code does not return a value. In this case, x is - 10 and this value is not grater or equal to 0. Given that the condition is not met, then the code stops executing and the value of y is none.
